Today I noticed that two of my questions were downvoted (the other day another one was, but that downvote has vanished). The other downvoted question doesn't matter, it was self-answered, not everyone's taste, no reason for a downvote but who cares.
But I can't explain the downvote on that one. And more importantly, there were comments to that question (from another user and myself) which are now gone. Yes, it was a simple "me too!" comment, but since when do they get removed? Was there a flag issued on the question and that's why the comments are gone? Am I paranoid?
Edit: Yes I know it's a vague question, but my main concerns are the vanished comments, and if they have something to do with the downvote, or if they are unassociated.
