Seems like very obviously labelled accounts are also being banned. H3H3 put up a banner with a poorly written bright red "parody" and replied to his tweets with "this is a parody account" and still got suspended
If PARODY between PARODY every PARODY word PARODY the PARODY text PARODY "PARODY" must PARODY be PARODY displayed PARODY that PARODY would PARODY be PARODY a PARODY really PARODY good PARODY way PARODY to PARODY ensure PARODY nobody PARODY was PARODY confused PARODY as PARODY to PARODY what PARODY was PARODY and PARODY what PARODY was PARODY real.

There's naturally gonna be a lot of places parody isn't labeled parody in blinking lights. It's comedically necessary. Ultimately if it is trivially easy for an average person to realize an account is not authentic (like the twitter handle being different) I think that's a fair and reasonable burden for anyone who imagines Twitter as a place where "humor is legal".
The person who does Safety at Twitter has been there for many years and he is pretty far on the “new left” side. Apparently, even he disagrees with you.
The assumption that it is a single person taking action against mislabeled parody accounts (like you suggested, by saying even Yoel disagreed with OP) is amusing, because naturally it isn't the case.
