Moderators of company forums like this are not allowed to support torrenting or discussions of torrenting, regardless of what their personal opinion may be, and regardless of the specifics in which you are torrenting.
Speaking as someone who has been employed as a Mod at a publishing company, I'd implore you not to argue about this. Mods don't make the rules, they simply enforce them. They aren't paid to have an opinion, they are paid to keep the forum as 'pleasant' and uncontroversal and positive as possible, so the company has a good image and isn't embroiled in heated debates over legality and morality. They don't want anything to do with that shit.
You're not being silenced, they just don't want it on their forums. They are well within their rights to delete your thread. Please don't make their jobs harder and more stressful. You can argue until you're blue in the face, but the simple fact is that Mods cannot change these rules. So just deal with it.
Read my first post and then reply with something relevant. :p
It is illegal to torrent software even if you already own a copy.
It really is.
A lot of the posters said that it shouldn't be illegal.
A lot of the posters said that it's not immoral.
A lot of the posters said that no harm is being done; that it's a victimless crime.
Whatever.
It is illegal.
Full stop.
The owner of a forum can and should set policy for that forum. The mods should enforce that policy. Unprivileged users can comply or find another forum; there are many thousands.
If the owner decides that there shall be no discussion of piracy,
so be it.
The mod was well within his rights and was doing his job properly.
