Has anybody else had a thread they wrote just outright deleted?

[LT7A]

I wrote a thread to point out that it appeared that the advertising links might be going awry. It was subtle. Initially made no statements. Meant to be humorous while raising the question. And when I added a comment that it seemed that administration may have made steps to improve it, poof! My thread disappeared along with any record of me posting to it. I've also had a thread relocated without any explanation except in retrospect. If it's going to be moved or removed I think that calls for at least a courtesy PM. I've always kind of wished for a big brother, ha, but Big Brother? Not really.
