The ads in question are "pay per click".
I've seen some pretty dumb ones too. Sometimes I joke that the ads on the site are IQ tests!
If they really bother you, send me the URL of the site being advertised - I can add them to a block list. A few years ago, I used to try to keep ahead of the obvious scammers by blocking them, but I gave up after a while because they often run under multiple domain names and kept popping up regardless of what I did.
