I’ve experienced something similar in attempting to report very explicit and outrageously racist posts and comments. Zero action on blatant neo-Nazism (including specific threats of violence), and several lost appeals. However, far more benign posts and comments that don’t really violate the ToS are often flagged. This is quite prevalent on Instagram especially, which is quite worrying as it’s acting as a radicalisation tunnel for large numbers of impressionable young people. It’s almost as if the algorithm attempts to throw you into a far-right rabbithole because they know it boosts engagement.
