AI is coming in, make no mistake, at the moment most AI sites (public ones) don't allow/support sexul content, but it'll come (no pun intended) both written, in pictures, and video. Already we have artifical backgrounds in video messaging, soon they'll be image inhancements (faces, hair), and then the ability to 'fix' bodies. At some point site like this will need to decide whether to allow AI, or if not, how to spot and block it.

The green issues raised by OP are another consideration, little-to-no thought has been given, yet IT becomes stronger in our lives and its resources will become ever hungrier.

Maybe not sexy, but food for thought.
