The legality of posting AI-generated images that use the likeness of public figures is also murky.

"It really depends on how the content is being presented," said Brent Mittelstadt, director of research at the Oxford Internet Institute. "If it's clearly being presented as a joke or as satire, then you're in a much stronger legal position."

"If something to a reasonable person would obviously be satire, then at a minimum, with things like copyright or usage of somebody's likeness, you can basically get around legal obligations in that way."
