Torrent sites gets mentioned on here all the time, as does jailbreaking mobile phones, modding xboxs, making "backup" copies of software/dvds. Some will argue that this should be banned but the world isn't perfect. Ban these threads and mods would have to remove any post that talks about vigilantism, boasting about speeding offences or drink driving, avoiding parking fines - basically anything illegal.
I have no strong feelings aout the threads as they don't make much difference to me and they probably don't make much difference to the site.
Why not complan about this thread - in my mind (if one is sensitive about this kind of thing) the thread below is worse
