Regarding the second and third points:
2. Read the forum rules first.
3. Create announcement with well organized design.
My advice to any casino owner who wants to advertise his service in this forum but he is not familiar with it is to hire one of the known managers to create and manage the Ann thread.
Regarding the seventh point:
7. Don't be too strict about your rules.
It's better to have a FAQ page and a clear and well detailed ToS page than to be lenient and don't enforce rules.

I believe Hamas use bitcoin and other cryptocurrencies to avoid sanctions and to be able to accept donation anonymously. But storing their coins on centralized exchanges defeats the purpose of using bitcoin in first place which is to be your own bank.
They should know better! "Not your keys, Not your coins".

Technically, you can't seize a crypto wallet because if the owner or anyone else who has the private keys can move the funds to a new one.

Honestly, Maus0728 with his awesome and creative artworks raised the bar too high for other contestants. Whenever I see his name in an art contest, I know he will be among the top three winners.
Personally, I prefer the type of contests where everyone can participate and have a chance to win without having a particular skill. The Guess the Slot was a funny one but don't know why they stopped it! I hope they will restart it or come up with similar idea.

If the instant deposits system is implemented correctly then there are really no risks and abusers won't be able to double spend or cancel unconfirmed transactions.
As I explained above, casinos enforce some requirements and impose some restrictions to prevent any losses because of abuse.
For example, replace by fee transactions usually won't trigger the instant deposit because they can be easily replaced. Also, requiring high fees ensure the transaction will be confirmed within the next few blocks. Most casinos that support this feature will not let withdraw while one of your deposit transactions is still unconfirmed.
Many gamblers prefer to use bitcoin which is known for its long confirmation time, this is why such feature is definitely a plus.

Thank you Jawhead for correcting me. I didn't know they have an announcement thread on bitcointalk, maybe because I rarely visit the altcoins board. My bad!

Yes, posting in their Ann thread or sending them a PM seems like the best way to get a quick response. However, OP's case is a bit different than the case you linked because he claims he KYCed his account and sent them all necessary documents. He also said that withdrawals were disabled since last August. I hope it will be resolved the same way, though.

There are few casinos that accept zero-confirmation deposits that I know of. Roobet, for example accepts zero-confirmation transactions. The last time I made a deposit, the balance got credited to my account the moment the transaction was broadcast (while still unconfirmed). Afaik, Owl.games support this feature too but didn't try it myself (maybe someone else will confirm this).

However, you should know that instant deposits come with few restrictions such as not being to withdraw till the deposit transaction get enough confirmations. Also, the transaction must meet some requirements to be eligible for instant deposit. For example, it must be non-rbf and it must be paying enough fee to guarantee fast confirmation. All these precautions were set to prevent the possibility of cheating by double spending.

Did they tell you why they suspended withdrawals for your account?
I can see from the first and second images you posted that their support responded to you via email but the images are blurred and we can't read the text.
Please, if you don't mind, post a clearer image or quote your conversation with them here.

I also suggest you remove the ticket number from OP. As Rikafip said, Kucoin don't have an official representative here on the forum so there is no need to share the ticked number.

Don't worry too much about this. There are hero/legendary members who still doesn't know how the trut system works and didn't customise their trust lists although they have been here for years.
It's good to ask questions and ask assistance and am sure many members will be happy to help. But, almost every thing you've asked about have been answerd in other topics. So, whenever there is something you don't understand and want to ask about, start by using the forum search feature or take a look at this thread:
Beginners & Help Encyclopedia [UPD: +Electrum Board]

In fact, it is quite the opposite. before the introduction of the merit system, members such as V3rtigo, didn't have to offer this service to others. All they had to do was to create as many accounts as they could, reach enough activity (higher ranks) then use them to participate in campaigns. This is no longer possible thanks to the merit system which made ranking up harder especially for account farmers.

I'm sure there are many others who offer this same service but they do it off-forum because they know it's frowned upon.

The funds will remain frozen in his account until the
U.S sanctions against his country are lifted. I just hope it won't take too long.
Locking customers accounts just like that and without prior warning sucks but it is what it is, sorry OP.
Personally, I stopped using Bitrex since the day they started enforcing identity verification.

"Prevention is better than cure." If the casino owners want to have a successful casino and be able to compete then the security of their platform must be one of their highest priorities. Besides, in case they get hacked they will lose way more than what they would've saved by lowering the security budget.
It's not only about money, if they get hacked they will lose the trust of their customers which will be hard to regain.

The "~" before the btc amount means it's an approximate value and not the exact amount you will receive. So, I believe if bitcoin price rises between the moment you enter the amount to withdraw and the moment they process your request, you will receive less btc than the displayed approximate value.
However, and since processing withdrawals may take up to 24 hours, it's interesting to know whether the final value/exchange rate used is determined at the moment you make the request (click withdraw) or at the moment they process the request (which may be 24 hours later).

The topic is eight months old but someone just bumped it. It looks like the website owner renewed the ssl certificate and the problem has been resolved.

https doesn't mean the website is safer or doesn't contain malicious content. It only means that the communication between your browser and the website's server will be encrypted. You should avoid http websites when you have to send/receive sensitive data.

This is Okay if you know and trust those who reviewed the code and the app/software has thousands lines of code. But, it's always recommended to verify the code by yourself especially if it's a short one. Remember: "Don't trust, verify!"
Even if you have basic knowledge of programming, by reading the code line by line you may spot a logical flaw or a vulnerability that other professional auditors might have missed either intentionally or on purpose. Besides, this will help you improve your coding skills.

Forum users tend to use the same username and add a suffix to it when they create alt acounts (a way to say this is my alt: theymos/theymos_away, hilariousandco/hilariousetc, LoyceV/LoyceMobile...). So, someone who didn't read this thread or didn't see the neutral tag would think Little Mouse created this alt for whatever reason!

LM, either he is up to something or, since you are from the same country, he is just a fan and takes you as example. But I would keep an eye on him nonetheless.
You did the right thing by leaving him a neutral feedback. It will serve as a warning for others and will absolve you from all responsibilty in case this user gets involved in shady activities.

Unfortunately, only the first website exposed in OP has been taken down (most likely by the hosting provider). All the other websites are still active except the last two that are active but blocked by Google Safe Browsing. Meaning that they will not appear in search results and if someone tries to visit them, he wil get a warning page that they are not safe.

I checked all the bitcoin addresses on those websites and all of them are empty and didn't receive a single donation meaning there are no victims so far, which is a good thing.

No, not necessarily. Some crypto gamblers don't know anything about the blockchain technology and how things work under the hood. All they know is how to send/receive coins from/to their wallets. Obviously hashwars.games isn't the perfect place to learn about blockchain, but some may learn a thing or two from it while having fun.

OP, since every thing seems to be working fine on the back-end, I suggest you spend some time to improve the website' UI and, if possible, make it mobile friendly.

As suggested above, a reputable hardware wallet is your best option. They are safe when it comes to storing cryptocurrencies and convenient for everyday use.
HW aren't that expensive but if you can't afford to buy one or looking for another alternative then you can create your own cold storage / offline wallet. Most reputable wallets support this feature. Here is how to create and use an offline wallet with Electrum, for example:

I beg to differ. This is the standard prize pool distribution (known as long tail) that most leaderboard contests follow. The first winner should get the biggest prize and 50% seems fair. Also, there should be a noticeable difference between prizes for each rank to make the contest more competitive.
Distributing the prize pool this way will incentivise participants and make them wager more to reach the next higher rank because the reward is bigger.

I never said that they will ban you because of changing the DNS server. In fact, no one who knows what DNS server is and how it works will say that. You can change it to whatever you want, you don't even have to use one if you add the website's ip to your hosts file.
What I said is that they will ban your account if you are from a restricted country or a country where gambling is illegal and the trick in OP won't help.

That's good but OP's situation is different. I believe he is from Indonesia and gambling activities, afaik, are illegal there.
