Bitcoin Forum

What happened:  I deposited .25 BTC using the address Fairproof.com gave me.  The coins never showed up.  After "Moderate" called out "FairProof" he vanished and moved the coins out of the destination account.  I can easily prove that the address that sent the coins is owned by me.  "FairProof" is unresponsive on this forum.  We could have easily resolved this issue.

Amount Scammed: .25 BTC
Payment Method: Bitcoins
Proof of Payment: https://blockchain.info/tx/d741691e71379900864ec41e50f287905a17ed211ddee6008c59cc6c0d47eecc

FairProof is a kind of bitcoin dice game. Website has no registration, user creates an account when visit website for the first time. Also he receives a unique url and bitcoin address to deposit funds for account. Account and url are connected with cookies, so if you'll switch off, delete cookies or use another browser, the system identifies you as a new user and provides new account with new url and new address to deposit bitcoins. Everything is described in terms of use.
 
We had multiple tests and about 50-300 users per day and the system shown excellent results. There are no issues except jberman73's.
 
According to logs and investigation of this issue, jberman73 created 2 different accounts, deposited the first one, but has url and related cookies for the second. It could caused by using another browser, or deleting cookies. The firs account contains the same amount of bitcoins, as he transferred.
 
In turn, jberman denies everything and trying to blackmail, post scam messages on forums,  send scam abuse to Hetzner - our web hoster. Hetzner has agreed to our arguments and didn't take any measures.   
 
As you can see, it's a user's issue and his fault that he transferred bitcoins to the wrong address or lost a url. We cannot divulge account and url that contains bitcoins to anyone, it's a matter of security. If the user will restore url, funds he deposited will wait for him. You can check the mentioned bitcoins wasn't spent.
 
We have unwavering position: we do not disclose user data.

Why not get him to sign a message from the address the 0.25 came from?

Yes, this site scam, don't play.

I have 0.12 BTC in my balance and I can not withdraw (minimum is 0.05) . I depoist 0.05 BTC and receive 0.05 BTC bonus, and then I bet total 36 * 0.05 ( for withdraw bonus ) and I can not withdraw. It said invalid data

I was surprised to read the accusations in scam since  I'd played at Fairproof a couple of times a few weeks ago and all went well (I did not win much but had no problems whatsoever).

Anybody else had a problem with them? I would like to know as I do play pretty often at various places and Fairproof seemed like a good place at first.

Keep me updated with how this goes, I think you should be refunded the 0.25 BTC

I did play more than once at fairproof.com, the last time a few days ago.
Not a single problem with them so far.
 

I really don't think it is a matter of 'studying' the case but rather a matter of confirming the OP did in fact deposit funds to your site. You should be able to keep track of all the deposit addresses that are given to users. The OP can simply give you the deposit address that he sent bitcoin to and you should be able to look up his account. He then should only need to sign a message from an address that sent bitcoin to the deposit address to confirm his identity

I did play dice myself at Fairproof and all went ok. However I'd rather wait for a successful resolution of this case before I play again.

 I was able to withdraw 0.5 BTC last week only. Slow support maybe?

I find it interesting as to how many newbie accounts are posting on here saying they have played "a few days ago" (this is what they are all saying) without any issues. While I have not seen any higher level accounts claiming to have played without issue. This would lead me to conclude that these accounts are shill accounts for fairproof

Call me whatever you will but I've played there multiple times without a single issue. They are sometimes slow to contact users, true - from what I read here, but never a scam.
