But you're right that if you mention the Dominion machines were "hacked", your comment is auto-removed.

If you mention that there is "evidence of fraud", your comment is auto-removed.

If you mention the elections were "stolen", your comment is removed.

If you mention certain word phrases around "ballot" and "ballots", your comment is also removed.

There's a long list of things you can't say across various social media sites. But on the upside, you get to thoroughly make use of a thesaurus to talk around the censorship.
