Here I will present the current list of ongoing scams in order to protect the community, it has been stripped of all non essentials to keep the community safe from scams, I will hold all Bitcoin businesses for full responsibility:

Legend:
Red - Most likely a scam.
Orange - Moderate chance of being a scam.
Yellow - Small chance of being a scam.
Blue - Was initially listed as scam, was whitelisted after review.


Just-dice I have analyzed this reported scam and it seems to be completely fair, furthermore it is being run by the noble "dooglus".

Strike Sapphire - Bad attempt at hedging against USD, they make a profit on their own rates. Owner is rude, no provable fairness. - Owner has contacted me, explained the situation and seemed to be respectful and honest, upon further reviewing StrikeSapphire I no longer list it as small chance of being a scam

Casinobit - Bets are delayed occasionally, some bets have invalid TXIDs owner has contacted me and explained the situation, the results are apparently streamed live now regardless of the feed.

Satoshidice - IS based on irrefutable mathematics that behave in an honest manner under normal conditions, sometimes bets are delayed by 24 hours giving the house the window to bruteforce a hash that will be the most beneficial, the house or anyone else that receives access to the secret list ahead of time can submit selective bets and get a significantly lower house edge.

Almost anyone associated with them speaks in an intellectually appalling language and is full of unapologetic loose cannons, except Voorhees himself.

Wheresyouredge.com - Pending review, DO NOT trust ANY bitcoin poker sites, there are currently none that I know of that use provable fairness.

MPEX - Despite the fact that the security never actually stole or scammed members the owner Mircea Popescu is a disgusting person that uses the term "nigger" on his blog while also constantly putting people down and generally being a complete snob. Lied multiple times about being the owner of a successful company, if it wasn't for Satoshidice releasing stock in MPEX this person would be selling potatoes somewhere in Romania.

SealsWithClubs - Uses ancient software, game-play connection is not secure.

SatoshiMines - Source of entropy is bad, the house can easily bruteforce the hash to make you win/lose. Including "random" non-preselected strings in the hash render the whole process insecure.

Bcpoker.eu - The lack of professionalism of the operators of this website is astonishing NO-ONE should play for real money on this website, I discourage any n00b for opening "mah vary own cas1no" and clearly people keep ignoring my advice as I see new entries of people looking to open a Bitcoin casino for a couple hundred bucks popping up on a daily basis. The owners are known to leak personal information. It is apparently registered by a teenager under the fake name "Adam Gergo Kovacs" as well as a fake address.

Bit777 - Misleading, calling themselves "industry leading" , not provably fair whatsoever, lack of verifiables of the actual bets processed, can potentially over-inflate their own statistics, a PHP Microsoft IIS/7.5 bot decides whether you win or lose. Encourages disgusting people to post sexually explicit posts that aim to lower the social status or attempt to make other members feel ashamed.

   
Bitcoin-Roulette.com - Shamelessly stole the CSS off another website, doesn't look legit at all, seem to have ripped multiple people off.

PrimeDice - Popped up a week ago, claiming to have totaled 11,081 BTC in wagers as of 26-May-2013, domain wasn't even indexed as of a couple days ago. NO verifiables of ANY bets whatsoever. I am going to assume that a fraction of the bets is actually real and others are fakes. Backed up by co-scammers like forum member Zaih that doesn't admit to be associated directly. The 28 page thread is mostly spam between 4 members associated with the scam.

Shilling has been shown to take place in the official thread, this will be obvious to anyone with half a brain.

As of now, Primedice is provably (un)fair.

Tradefortress - Member "Tradefortress" added to the list as per his own request, enjoy your time here you glorious winged douche.

BitcoinVideoCasino  - Fake statistical data as well.

Ripple - Pyramid scheme, homepage contains blatant lies, complete misrepresentation.

Butterflylabs (BFL) - Apparently manufactured the ASICS and mined with them themselves instead of shipping them until it no longer became profitable, owner is an ex-con (and not the good kind either) who has been convicted of mail fraud, forum members inaba and BFL_Josh are fellow fraudsters.

Cryoniks - This sums everything up nicely:


BitBet.us - Seemingly innocent but will scam and make money off large bets, forum member MPOE-PR is related to the scam, SatoshiDice is also related to the people who run the scam. The group of people that run the scam are mostly trashy, condescending and prideful for a reason that shall remain a mystery to us. It appears that this is the reason why the reputation of SatoshiDice was questioned by other forum members like "mem".

Bitbox.mx - Fraudulent, deceptive Terms of Service are no excuse to hold on to the funds of the customers while demanding official documents out of the blue. The customer should be able to get a refund in case he refuses to provide the documents. https://bitcointalk.org/index.php?topic=227121.0


I will occasionally dig up all the trash on casinos/services and post it here publicly.

EDIT: New websites are popping up everyday, the general rule of thumb is stay clear of any non-vet website and apply common sense.
