Yes, I have had the same problem - with "rare" searches. I did download one of these files and it was one of sexual content. I don't know if all of them are, but I won't download another file of that nature.

Mr. !_! is a real tradition: it means you've downloaded another Limewire version and the banned host list now has to be re-entered. This is just porno spam, but a real irritant nonetheless.
