What about a joint ops theft by the Bear and LFIATT. He has had a low profile of late so I suspect he sneaks on the board at night and steals posts from threads no one is looking at. Just the type of behaviour you could expect from sub-par punners.
There's no such thing as the Deleted Thread Repository. Just ask Goober, he's been banished there, he should know.
There is, however, the Moderators Annual Bonus Plan where Fred divides up all the freebies he collects from advertisers in exchange for deleting all their negative reviews.
