Why would a thread get dumped when the only purpose of it was to help others?

I saw the thread posted by Kern Dog and thought it was a great way to help someone else out that might be needing parts, and no different than any other posts that I've seen and sometimes even made myself.
Having said that, I have made a few posts recently that have been edited with no reason given. It's possible that, as others have stated, that there's a new censor in town, that can only lead to less activity on the site as interest wanes, which would be unfortunate since this is by far the most enjoyable and informative automotive sites that I have been a part of.
