Local group on Facebook for finding houses and apartments, and hundreds upon hundreds of comments on every single post for the past couple months are completely AI generated scam spam links. They are probably using the API version of GPT4o, and break even off of scamming enough people.
Text is identical, this is not AI, more like a cheap autoposting script. If AI was actually used, it could generate wildly different text every time, it could even use what user said in some post as a context to suggest something to him. That would actually be the only reason to use AI here.
