ive used torrent sites for years and never used peergaurdian or any thing like it,and never recieved any emails or letters from the man. as long as u set it up right and try and stay away from public sites such as pirate bay u woulnt either.
private sites are way better anyway my connection speed is 20mb with bt and i download from a few different torrent sites i use at 20mb.
the only trouble is though most private sites are invite only and u dont get many invites from the admin,they do however have open sign ups every now and again where anyone can join i posted about one at christmas on the other board (wasnt a member here then)when they do another one ill post it here as its a cracking site and can get almost anything u want (i searched for monkeyface after hearing about it here but alas no joy
)
oh i might have a few invites for demonoid if anyone is interested,cant check yet as demonoid is doing thier usual maintenence.
