Interesting, I've seen some articles on doing stuff like that. Not sure if that was the case here but interesting none the less.
On another note, when seaching for "proxy", where or where did proxy.org go?
Don't know, the Google dance maybe, can be also deindexed because they ask money for their links, a lot of money, i think Google is known for deindexing paid directories / link indexing sites. Not sure but will see what's happening.
