pashatfo: I'm not actually sure what's causing the problem, however you need to change ALL of your passwords immediately - you just posted them to a publicly accessible forum. That is not a good thing at all.
As far as the backup folder goes, I'm not actually seeing one present on the account, but it's unclear who actually removed it at the moment. I am investigating to see what happened however; miaox10m: under no circumstances should you ever be accessing another user's account, period. If you caused damage to the account, expect punishment shortly.
Edit for note 1: miaox10m: When you are ready to provide a detailed explanation of EXACTLY what you did while accessing the account, utilize the suspension dispute system to do so. Failure to provide a good explanation will result in your permanent removal from the service, as your actions look to have caused the deletion of user files on a hosting account which was not yours.
