If you really want to post about how vaccines make your blood cells broadcast 5G radio waves, you can go make a Parler account regardless of whether you get "unpersoned" (?) by Twitter.

Twitter's rules enforcement is historically EXTREMELY casual, the only thing I can think of is that they are relatively consistent about punishing death threats regardless of context. Even then, they let some of that slide. Very often a rules violation just results in a tweet being deleted or marked with a disclaimer, not a ban - few services would treat rules violations that way.
