Academia.edu's terms of service are so evil it's almost funny. I'm surprised they don't make you give them your first-born son!
But it looks like they mean it. I'm reading people saying things like:
"I quit it when I got an email saying they had generated a podcast using AI based on one of my papers without my permission."
and
"I got off academia dot edu 5 or so years ago, when I discovered it was sending automatically-generated emails in my name without even telling me - I found out when a very senior member of the profession replied to one."
