Are you really trying to say that you've only had one account on betcoin.ag? And that your ip wasn't blocked due to multiple accounts? I don't have the time to dig up all the evidence....Just suffice it to say, you seriously lack credibility.
Creating multiple accounts when your accounts have been banned in some way in order to use the chat feature is not "multi accounting". Multi accounting refers to making multiple accounts in order to play in the same tournament or cash game in order to take advantage of the other players. If Twitchy has been doing this, that IS a problem and if you could show evidence of that it would go a long way to damage his credibility.
