If he has - and I think he has based on one particular tweet where he said someone 'deserved to be harassed' - then he should be banned or suspended. Not 'unverified'. Not given a link to the ToS without at least one specific incident.

Conversely, the person whose previously doxxed him - also violating the Twitter ToS - should be punished too.

Twitter just need to have a concrete set of rules (objective not subjective) and enforce it consistently regardless of politics or celebrity status.
