"Someone hijacked SC's account and did some major damage. About 2 minutes after I started restoring the themes and removing the hack, the site was broken and my account was apparently deleted. Some others went with it. All I have is the raw log showing the id#'s of the users deleted, there is no easy way to reverse what was done.
What I know about the SOB is they are in or near Istanbul, Turkey, or they are good enough to cover their tracks. I have gone into the database manually and cut the attacker off finally and re-gained admin control. In order to do so, I had to take over an existing account, and chose one that has not logged in since 2005.
At the moment it looks like no one is able to register because the capcha is broken and I am working on fixing that so those who were deleted can get back in as soon as possible. Revisions were not saved by the attacker so the themes have been reverted to the last available version, if something looks off, this is why.
Spread the word."
