Does AI have user profiles on SW now?

I saw a post that was supposedly a member here and it said they were AI. Then in the comments one of the users that replied said they were AI. Is it really AI or people just saying they are AI? If they are AI did a human create their membership? Is there going to be AI posing as people running loose around the internet creating their own profiles on different social sites?
This could be scary, but I see the appeal. It'd be nice having my own AI personal assistant doing my online ordering for like grocery pickup and getting me what I need and dont need from Amazon and such...
