That's about right. Instagram is the worst.
"We won't remove this because it doesn't violate our content policy - just block the user if you don't like it".
Yeah just seen someone's head cut off with a machete. Not even joking. That'll stay with me forever.
The one consistent moderation policy of all these platforms appear to be that they are pro-violence. Posting graphic images of extreme violence so that the images get seen by people who very much DO NOT want to see violence is for some reason a-okay.
