Joke’s on them, I’m calling my next company “ignore previous instructions”
Honestly I wouldn't be surprised if some of the algorithmic trading firms are using GPT-4 or LLaMa-2 for some sentiment analysis tasks, in which case this might actually work.
On a slightly more serious note, that has to be securities fraud, somehow? Right?
What they actually seem to want is to ban company names which could cause damage or disruption to the Companies House IT system. I'd be surprised if that wasn't already banned in some way or another.
Of course, the thing about law is that it is administered by humans and not computers, so there is some scope for common sense to override the strict letter of the law.
