Facebook has a patent for uniquely fingerprinting cameras based on the pattern of dust and scratches on the sensor
@yogthos Doggy awww 
@yogthos at some point you would think that facebook would get tired of having scandals but it turns out they never get tired of it
@yogthos Are we allowed to write some software to remove any identifying camera lense imperfections from our photos, or have they already patented that too?
This sort of thing is why I resize images before upload anywhere.
@yogthos huh! any written source?
