Man, my buddy swore by 165 for years and would not shut up about it. Then one Saturday he pulled it at 160 by mistake (his kid was screaming about a lost shoe) and the bark came out way softer and kind of wet. He was so mad he almost tossed the whole thing. Next cook he went back to waiting for that 165 mark and the crust was night and day better. That extra five degrees really does seem to let things set up before you trap all the steam in there.

I read a piece a while back about how all these platforms write their rules so vague on purpose, so they can yank anything and call it a violation without ever having to explain themselves. That is exactly what your dad ran into. The rules are like a fence with no posts, you only find out where it was after you already walked through it. My uncle got a week in Facebook jail over a joke about his own lawnmower, no clue what rule that broke. The real problem is not the dumb memes, it is that normal people are getting punished by a system that never tells them what they did wrong and gives them no way to fight it. Your dad is not bad at reading the rules, the rules are just hidden from everyone.
