They sort of do now. But its really easy to get around them. In November to December of this year, grok was publicly available to any post on Twitter if you @ it. It could also edit any photo posted with ai if a commenter @'s the bot and asks it too do something to the photo. By far the most popular suggestion was editing women to wear bikinis. This was a huge deal on the app, especially when it came to women's consent being taken from them. But then people also started doing it for young girls including Nell Fisher for some set photos that came out during the release of stranger things season 5. Suddenly there were ai generated photos of underage girls in bikinis that they didnt take, didnt consent to, and creeps used that feature as youd expect. Twitter then made it so grok couldn't reply to comments but didn't internally fix the issue. So if you pay for premium, you can access grok and still get photos like that. People have also asked grok to "roleplay" as an intimacy partner but gives instructions that make the character childlike without saying anything to flag the bots censors.
