Those are hard to find, but it has been going on for years. I report them with "Spammer. Nuke please.".
Sometimes not. Here we can see a message left three and a half years ago (
I deleted link in a quote not to help a spammer):
No, I think Anyone is not a writer here.

Because I've definitely seen shit like the link jokers10 pointed out, but not the AI-generated post with that code OP described (that I know of anyway). Have we got a new form of link spam here or what? I ask this as someone who is not a coder and is basically an idiot amongst geniuses when it comes to this kind of stuff.
I do agree that bitcointalk has been the stomping ground for all sorts of spammers for years, though. I've seen all kinds of it, and a few years ago there was some group (or an ambitious individual) that was posting advertisements for mens' products and other garbage, and I recall doing a lot of reporting back then. I'd support anything to cut down on this shit, because the quality of most discussions is lousy to begin with and we definitely don't need SEO spam being inserted into posts and going undetected, thereby encouraging spammers to keep doing it.
