Spammers posted OP's from catalog threads I was cleaning, running thru quickly. In this way, the 11 pinned resource threads were deleted. My sincerest apologies, am very tired but still, it was my mistake and my responsibility.

They are likely restorable with thread links but nothing is certain when it comes to digital data. However, a similar situation resulted when a BV purposely deleted most of the files from the catalog. They were restored within the day. Hope these threads can be simlarly restored.
