The member in question is currently under investigation, as others said we believe that he/she was a troll, who may/may not be a repeat offender. I didn't delete the thread myself, but I believe that the reason for the member's posts being deleted are due to the content of one of his threads in particular not being family friendly, or within the rules of the forum, and the overall content of his posts being suspicously similar to that of a troll.
