I don't think they use picture analyzing software for tracking. It's very resource heavy because it uses systems similar to LLMs. You can make very slight changes to your pfp (just one changed pixel is enough) for every website to avoid hash match but it's not necessary I think. If someone wants to manually find your accounts though then it won't be too hard for them.
can't you quantise and downscale the image, then take the hash?
That works too but then the image will be the resolution of a Minetest texture after uploading.
no i mean downscaling and quantising before taking the hash to be able to reliably get the same hash for images that have been compressed, downscaled, had individual pixels edited, etc
Oh that's smart but I don't think they use it for tracking now. The most they can do is check the hash for known CSAM.
