It is only a paranoid rumor.

Doesn't the RIAA (who sues some P2P users) use clients to vew who connects to tem? That way they get users inetrnet addresses which they can then get warrants for ISPs to link to customers.

All clients are vulnerable to such an 'attack'. But AFAIK RIAA has only sued Kazaa users while they continually try to bring down ed2k portals and torrent hosting sites.
