we've seen a few DS tweets recently with 'FF' in them (fried fish plus a couple others… can't quite remember but they would finish with 'freaky Friday', 'french fries' and similar).
The obvious inference would be FF = false flag. But I'd be amazed if deep staters were that lazy in coding their comms.
Maybe that is all it means, false flag, and they are having to encrypt poorly due to not being able to meet in private to agree on a system of encoded comms.
