What's wrong about paying for reviews? It's something every company does and it's incredibly common on the web. You want to refuse services of every company who bought views/reviews/trafic or things like this? Your choice but it's going to be tough.
For the stealing of 10's of btc... I'll look into it but I seriously doubt you. They're a huge casino with excellent reputation. Why exchanging their reputation for 100 btc?
They pay players to leave reviews which appear unsolicited and genuine, all the while ignoring all of the allegations I listed. I believe this is unethical and I don't think every company does this, but if they did, I don't see how it would affect whether it was ethical or not.
As far as the theft:
In each of the biggest examples I've proven, the funds were initially taken unintentionally (they claimed this, and I believe them) They were taken by over raking cash game pots, so it went on unnoticed for a while. Once it was brought to their attention rather than return the funds immediately and fix the issue causing the over rake, they did nothing and continued to over rake for weeks or months then attempted to cover the issue up or simply ignore it - either way it's clear they plan on keeping the funds, so I think it's fair to consider them stolen.
Read the accusations objectively, I'm interested in and will respect all opinions. So far those who have supported betcoin after reading the accusations have either just ignored me (like betcoin.ag and ftwbtc) or resorted to calling me names.
