Right now, they are deleting some adult flash games.

The owner answered that it is for copyright reason.
(they deleted my games, but i had the permission to use the pictures)

It is ok for "original hand-drawn content"

He also answered that "My thinking is that I want to support anyone in the community to happens to draw adult content, but won't be supporting photographic nudity and won't be encouraging adult art that did not originate from within the community. "
