Actually, all AIs have guards in place to prevent that kind of abuse.. anyone who has tried to make ChatGPT say lewd things has figured that out a long time ago. It's more than likely one of Elon's tweaks lifted some of those restrictions.
I mean, that's shitty, but there's no way in hell it's the worst thing she's had tweeted to or about her during her tenure. If all the insanity spewing from Grok and X users up to now didn't phase her, I'm guessing she's not bothered by this either.
(Not to say she or any other women deserves to be talked to or about like this. But by now people working at or using X know what they're involved with and have made a choice to be there, so they must be okay with it at some level.)
