It had very poor viewing/listening figures for quite a long time, and was generally seen as a bit of a joke, but they’ve been growing alarmingly in the last year - though still comparatively low.
If you see a report saying “GB News hits 1 million viewers”, note that this was corrected a few days later to “actually it was only 33,000”.
So currently, it’s generally not trusted or respected, and is kind of seen as a joke, but like UKIP, Brexit, Boris Johnson as Prime Minister, Donald Trump as US President etc, it’s a dangerous joke that we should be taking more seriously.
Though I hope to not see them, I think it’s a great idea.
Perhaps a selection of British TV or comedy characters could do the job - bouncers and policemen, detectives etc should cover the various bad/forbidden/unauthorised/not found etc.
Perhaps a Basil Fawlty attacking a bad gateway with a tree branch?
