First I thought I only would if it's someone I talk to, but if it's anyone I can get in contact with I could just make a throwaway account and send them the link. Not important they know who's telling them as much as it is that they know their stuff is leaked
If it looks like someone posted them w.o their consent then 100%, If they put them up themselves then no b/c I'm basically saying I found them while I was beating off lmao
Depends on the situation for me. I would say if it was posted without their knowledge then I would tell them about it, but if it was their own doing I wouldn't ever bring it up.
