I have some good PDF ebooks I’m willing to share, but I suspect the seller embeds some tracking data in them to link them to my account, as every time I download them from the official website they have a different hash while being visually identical. The same when checking against the copies a friend bought from the same seller. Since I dont wanna get banned, can you recommend a way to remove that stuff?

Could look into using exiftool, qpdf or pdftk, if you are comfortable with the terminal ✨
qpdf is very powerful. If OP is comfortable with the terminal, I’d recommend qpdf.
