A big long post on the 2+2 thread (since deleted) from someone who said they used to work in FTP's security team said that Sorel was banned for multi-accounting, but has been playing loads on FTP since under many accounts, using ever more sophisticated methods to disguise it (including one big tourney where there were numerous new accounts all playing from the same IP address which were strongly suspected to be him). Think he said Sorel had shipped an FTOPS event under another alias, and that he strongly suspected him of multi-accounting on Stars as well.

Wish I hadn't refreshed that page...
