If the bigger camsites would take action against the auto capping sites hiding face would not be such a deal like it has become.
The internet is WAY to big for that. Protection and security is always a cat/mouse industry. They luck enough there are even basic legal rules that can be used to do anything at all (DMCA takedowns).
Hiding face is only a big deal for people that make it a big deal. If safety was completely guaranteed in this industry nobody would be make as much money because it would be flood with may times more models.
