I have terabytes of porn on gdrive spread across hundreds of different free gdrive accounts. I opened those accounts when it was still easy to create new gmail accounts like a decade or more ago. Basically every time I downloaded a bunch of porno I uploaded it to a gdrive in case i wanted to see more than 5 minutes of those movies. And when it was full i just opened a new account. Non of those accounts have been flagged or taken down, except for inactivity. You can have porno on gdrive. They probably put their private “but she’s a thousand years old” kind of hentai on there and got flagged by a bot for CSAM
