Finding them isn't hard - just go Surfing.
Identifying them isn't really hard, once you've seen a few.
Here's an obvious one.
Aff Friend Finder (this one is dead, now, so I will show it to you).
Note the URL.
aff-friend-finder <== Name
wvghpcb <== Suffix
Obviously, being generated by a script. Names are very brief (1 - 3 words, English). A suffix of random alphabetic characters is appended to the name, giving a unique URL.
The template used is a pattern too. Frequently Rounders, or 897. Monochrome backgrounds, no customisation, very plain. A single linklist at the top of the sidebar, the last item in the linklist will be "Friendfinder", and will link to "AdultFriendFinder.Com".
The content is another story. For a long time, I thought that the blogs that I was seeing were hijacked from existing blog owners, and were legit content, though a bit random and scattered subjects. Then another blogger showed us what we have.
Scraped content. Scraped from other blogs.
But, it's scraped content with a payoff - a payoff that you don't want, and may not see immediately. If your computer isn't properly protected, with a robust layered security strategy, you are possibly now a part of another botnet.
