Great idea.
I will only post that a website is fraudulent if sufficient proof is present.
First example:
Will be added to evil list.
http://www.coinfinance.com/news/dicebitco-in-unmasked-as-a-scam-as-casino-steals-over-3-million is sufficient proof.
Second example:
Link leads to primedice which are pretty solid. Unless you can bring more evidence of malpractice, I will not include them in the evil list.
Dicebit.co.in.
This topic is a very good idea it will help to avoid more scams from this websites maybe some admin can pin that topic

Thank you, this is exactly what I am trying to do here.
I bet on dicebit.co.in, I was doing anywhere from 0.1-4 BTC bets on 10x payout, and when ever I was due to win the nonce would skip and give me a different number causing me to lose. I verified all my bets where the nonce skipped and they were all winners. If their code wasn't rigged, I would have walked away with 61.8 BTC. So yeah, I'd appreciate it if you could include them on your list. I can provide proof if needed.
