Maby just delete your note, when you get to see, that it is flat out desinformation/misinformation or so

You can’t delete notes on Primal or Damus
Ok. Not even within an other client.
Which ones even support delete?
There are some where you can request a delete, like noStrudel, but it's just a polite request to relays to delete the note. There's no "hard delete" in nostr; it just doesn't work that way.
More on delete requests are described in NIP 09:
