Google's Ad program: https://www.google.com/adsense/
Spammers like to use it on their spammy sites. Antispammers like to get their accounts suspended.
Am I understanding this correctly? To benefit from using AdSense the spammers are hoping that a user will not only follow their irrelevant links from the wiki / blog, but also follow more links (the google ads) from that page.
Can't be that many users who do that. I guess it depends on the type of spam, and the type of spamvertised website. The majority of spam I've seen is linking to weird link-farms which are not at all designed to be enticing to a humans. But I suppose they sometimes just slap in some google Ads on the off-chance. – Halz - 2005-09-06 11:21 UTC
Halz, the goal isn't to be enticing to humans per se, I believe the goal is to attract the Google search engine. The revenue stream works as follows:
Even if the revenue stream is small, I suspect it isn't hard to earn more than the yearly domain registration, so if you've got a thousand such sites you probably can make more than a few bucks. – RichardP - 2005-08-08 09:20
I don't know about AdSense, but some ads at least used to also get pay for visitors just viewing the Ad. – Joe - 2005-09-06 20:11 UTC
