The situations that drive me nuts are the conspiracy idiots who zoom in super hard on some heavily compressed image they pulled off of the web. They then proceed to claim that compression artifacts, optical flares, noise, etc are evidence of whatever crap they are pushing.

Taking things out of context is another issue. It has become painfully common online. I would see it all the time when pushing the "all police are bad!" narrative. They will deliberately edit out the violence that triggered the arrest then make it look like the arrest was unwarranted and overly physical. People will do this with dashcam videos and show road rage but edit out the part where they triggered it with their own aggression.
