Sounds like you'll need to embark on a "reminder of TOS" posting campaign. Use short sentences. Make statements, not explanations, and indicate a zero tolerance.
Remain on topic.
No personal attacks.
No (whatever else that is restricted)
No warnings are given. Failure to comply with the above will result in message removal (or account termination).
Do NOT get involved in "free speech" arguments as that is a rabbit hole with so many tunnels (different countries etc) you cannot win.
