Interesting site for sure, but I'm wary of A) the legality of it and B) the length of its existence...

It seems to have a weak contact section, with no names, business address, etc. available to users.

A cynic might also suggest that it makes it harder to know who to prosecute.

Its mostly ad driven, revenue is almost certainly generated via ad hits and click throughs...

I suppose I'd say enjoy while it lasts, but don't be shocked someday if its gone...
