Just throwing this out there, maybe on massive platforms like this the better approach would be

- let users flag posts

- more than X flags = autohide

- original authors can object to the autohide

- objections are reviewed by staff

That would limit the content reviewers have to see to stuff that people (a) declare authorship for, and (b) claim is acceptable.

Presumably anything posting anything horrible wouldn't choose to have their posts seen by a critical authoritative audience.
