Sorry, Jemima, you're hardly the only poster here who's been to the Ed Fringe. The first time I went, I was with my parents. I was 16, and can assure you that the very last thing they wanted to do was take me to see any racy shows involving nudity. They still did though. Because contrary to what you say, it ISN'T generally flagged in advance. The vast majority of plays or comedy with nudity do NOT flag it on the blurb, any more than they flag the plotline or a comedian the punchlines. Sure, if all characters are completely nude for extended periods of time. But a bit of light nudity? No.
It's also blatantly complete nonsense to even begin to suggest the Pleasance didn't know what they were booking given he'd performed there for the previous 30-odd years or the staff didn't know him by reputation either. It's a famous comedy venue and he's an incredibly well-known comedian - I'm no comedy buff but I'd certainly been familiar with the name for years. Anyone who chose to work at the Pleasance - and the jobs must be competitive - would be a comedy fan.
And google exists - hardly as though it was impossible to find out he was beyond outrageous and his show involved nudity. The adverts for the show on YouTube - because of course no-one who goes to see a comedy show these days thinks of looking at a clip of the performer first, do they? - here explicitly say 'he gets his dick out'. I don't know how much more blatantly clear he can make it?
You also make some - as far as I can see - entirely unsubstantiated claims the nudity was aimed at a particular woman who was distressed. Do you have a link to this? And that a woman was distressed by being made the personal butt of jokes by him. Again - do you have any proof, because I haven't read anything anywhere else suggesting he either did this on this occasion or has done this previously.
I haven't seen his comedy and it's not possible to view any of his material other than the Jimmy Savile reference online, so can't comment on how it comes across. From someone who clearly has seen him, though, I thought this Twitter thread was interesting. twitter.com/ExcelPope/status/1558942459853422594
It points out how hard it is to tell from a reference to a single word out of context who the joke is on.
And it's not clear to me that a line was crossed here, when apparently it's not been crossed in the last 30 years (and his only previous 'cancellation' was for outing Jimmy Savile).
Maybe he is guilty. But it feels quite weird, tbh that the Pleasance, or a supposedly distressed audience member, aren't making it a little bit clearer exactly what it is he is supposed to be guilty of. If it's actually as clear-cut as you claim.
