No offence but none of this makes since, would you like to spend possibly hours to find a decent model, that 1 Isn't broke, 2 Looks decent, or 3 fits rp. You don't want to spend 100's of dollars and tons of time for someone to just come and steal the model that you seek'd out. Also I don't believe copy write was mentioned once, this is just like a personal thing from what I can tell. I don't think a single person wants to have to deal with someone "stealing" your idea's/stuff. That is my opinion.
Also +Support to this, after all the money and time I have spent finding models, I would prefer they are not "taken" and used by someone else. I am not kidding when someone threatened
to buy a copy of my class, just because they wanted to get under my skin.
