The NatWest / Coutts / Farrage affair is going to be an interesting case study in dealing with trolls.
If the CEO of NatWest simply said No Comment, and let their dealings descend into to GB News dribble, she would still be in her job.
Instead she tried to defend her company, and broke privacy laws in the process, by saying Farrage dropped below their deposit threshold for having an account there. It's kind of like those people that leak military secrets to win a world of tanks forum battle.
