This is the last post that was deleted today, I can't see any single reason for deleting it.
According to his post history, @len01 is a clear case of a signature spammer. Your post history looks much different, so you shouldn't be comparing your posts to his.
You'd better open your own topic and ask the moderators for their opinion, because I don't see any particular reason for deleting your posts. It's possible that the moderators made a mistake in their assessment. They're only human, after all.
