I imagine that $9k ad revenue is a site that had an actual user base. And that the guy taking over the domain is going to just put all ads and no content, like he had on Friendster.com. And if so, the expected ad income is probably much lower.
I believe it's 9k/year in parking revenue.
Exactly, and the fact that friendster failed was because nobody was going onto it anymore, so there's nobody going to be hitting ads, other than bots.
The WayBack machine shows the redirect to the ad page offering the domain for sale.

So doesn't seem like it was serving ads anyway
