Since that log on the BT can be viewed by anyone freely and openly, I think anyways, it's already in the public. This is opposed to a private chat log stored on your hard drive, that only a few select individuals can see.
So the first can be allowed since it's already freely viewable by the public, while the second, all parties involved must give consent before it can be posted.
Make sense?
In either case, Devs kinda can do whatever they want to a certain extent.
And while I'm answering off topic questions, Veng, a forum admin, cleaned up the thread as he felt fit. Myself, as a forum mod, who "works for" the admins, do not feel the need to go against their doings, since well, it's their forum, and I just help run it.
