This is interesting- ynot closes wutznew and superlinks

[Bill]

There was a time when I made a lot of money with this traffic...

http://www.ynotmasters.com/azone/affiliate_closed.html

At a certain point it became too much of a pain to get sites listed there, and I moved on, altho I still have old sites getting traffic from their toplist.

Anybody have any theories on why they closed? Their annoucement is nearly information free.
