I did review the post in question. It was a reply to another post that was removed. If somebody posts something against the rules and 3 people reply to that post in response to clean up the thread we remove the original post and the replies to it. If we didn't do that then the thread would still contain parts or content of the original offending post and/or the follow up posts would no longer have any context.

This was the case here. All replied to someone else's post which was removed. As part of the cleanup the replies to that offending post were removed. Al's was one of these. It was explained to him this was the case but obviously he doesn't agree with our methodology.
