I have particularly enjoyed the "Things were said about you" line they have come up with without saying what was said, Its a version of the triangulation manipulation, where outsiders are brought into a conversation but you don't know who they are nor what was said... It just says so much about the person doing it...
But as for plumbers...looking at their posts on common plumbing issues I would suspect that they are not really plumbers but have just faked some credentials... any real plumber would tell you direct to your face.
