I don’t think any report I’ve ever made on a social media platform has ever been accepted. I once reported an account on tiktok named “[swastika symbol] FATHERLAND [swastika symbol]” that posted holocaust denial and genocidal content and got back “no violation detected”. The same is true when I reported similar accounts on twitter (even pre-musk), and Facebook. I don’t even know what the point of the report feature on those sites is, I’ve never even heard of it working.
The hurdle I see to that is not necessarily changing system myself, but convincing my playgroup to change too. It’s hard enough scheduling the group, let alone getting them to learn a new system!
