The owners of ProBitcoin.org are SCAM ARTISTS.
  
INDISPUTABLE PROOF CAN BE FOUND HERE - http://cur.lv/5tyh7
  
ProBitcoin.org was previously operating under the domain name: ProBitcoin.it when it was revealed to the public that the owners were SCAMMING their members.  When this came to light, Probitcoin.it was quickly shut down and reopened with a new domain name: ProBitcoin.org
  
Again, INDISPUTABLE PROOF can be found at http://cur.lv/5tyh7
  
DO NOT BE FOOLED BY THESE ASSHOLES.
