Beside fighting with abusing free satoshi system, they are also using it to prevent loss due to Multiply BTC game. I've asked similar question long time ago that A) similar case which multiple accounts being used to claim the Free BTC vs B) multiple accounts but don't claim a single peny but to be used for Multiply BTC game only... the second case was not an abusing case but violated "one acount per user" thus users can't have an easy way to beat the system (don't hope for William Hill like which you can play multiple hands).
Where did I say that?
will you give me at least a screenshot in private messages, where do you confirm that all accounts have been registered with one user? Dont ignore me, Im not asking for anything bad
