Google does follow every link, and those people do notice, because their forums get deleted. Very few people do it this wrong for very long.
(Or they get fed up and patch the problem without understanding it, by using robots.txt to block all crawlers from their site.)
There are links that do that and if google were to follow every linkt people would notice very fast.
