It is about as underhand and devious as it comes, pasting a link to a thread showing the newest posts first, so that it looks at first sight as though the last 8 or so posts were not from the same monomaniac.

A look at the first post in that thread - Closed threads and deleted posts   will now give the impression - from the spam posts dumped there unbidden by the current Chief of the Mudcat Editing Team - that the first poster to that thread was not its orgininator but someone called 'porn' or similar.
