Last year when he started his bitpoker.biz website, I registered as an affiliate. For each visitor to his site he promised to pay 0.002 Bitcoins. According to his own affiliate statistics, 3673 hits were counted for my ref-id, 2350 of them unique visitors.
Additionally, I earned 7030 "bitbetter points" on his website which were promised to be exchanged with a ratio of 1000:1 into Bitcoins.
All this happened last year. I sent him several PM's on this board and emails to his address (which he used to reply to before), asking for my payment of 11.73 Bitcoins. He decided not to reply and went into inactive mode. A few days ago I noticed he is active again and once more reminded him, offering to solve this without making it public.
He has been on here since I sent the PM and so far, there has been no reply, no email and of course no payment.
So if you consider doing business with him, be careful.
