Nope I am not talking about PBMining, but makebtc.org and ponzicoin.co.
Please click the link in my above post and you will see what I was talking about.
Yeah, I also saw some ponzi sites in the ad spots before, and it's not PBmining, it's other scam sites.
Actually ads should be censored, and admin can reject scam sites if the admin rejected bitmixer before, betcoin.tm is a notorious scam so they should know it.
