If it's free to use and abuse the model and the creator says so in the AUP then fine, upload it here with a copy of the AUP, hopefully crediting the original author too.
We can't allow questionable media to be uploaded here, by questionable I mean media that doesn't come with the creators permission. How do you think the creator would feel if he thought that his church was being given to FPSC users for free, that's the same as EA taking one of your models and supplying it for free for one of their games.
