A couple of days ago a series of Threads along with their posts disappeared from my forums. At first I thought someone had blown them by accident but I went to check in the logs and there is no indication they were deleted by the other admin. I have pretty much turned the site upside down to see if they were purged or deleted, but to no avail I have not find trace of them. I also checked the DB and they are not there either. Can someone help me brainstorm what happened?
