Old users.
 

Well It seems like my old acc was deleted here. Is this becouse i (stupidly) uploaded a file to the ftp that was not splitted into smaller parts. Or is there any other reason?

I find no listing of that name in the search function. If you will read this Thread:

You will see that Aaron has set a policy which deletes those users who do not visit within a year and/or do not post within 6 months. It is most likely that you failed one of these two tests and your prior user name was deleted and any posts by that name are now marked as "guest."
