why did tfabris delete one message?

Actually, Mark deleted the message first. It was an outdated version of one of the links. In a subsequent message, he posted a newer, better link.

When Mark deleted the message, it left a placeholder behind which said "message deleted by mlord".

I thought that, since I was an admin, I could clean up the thread by deleting the message completely and that would leave no debrid behind. Well, it still left debris behind, only now the debris makes it look like I was censoring Mark. Actually, I was just trying to clean up a bit of a mess.
