Getting an ID on a 'bot, AI, or AS can be tricky. I've been watching the one that behaves like Eliza for some time now, and the "writing style" is rather distinct, and the content is remarkably lacking being mostly readbacks and paraphrases of readbacks. The one I'd tentatively classed as AS may just be a human with Asperger's Syndrome; telling those apart is almost impossible.
One clue that you may not be dealing with a human is when a long-dead thread suddenly lights up again with some sort of content-free post.
Wikipedia has a decent write-up on "chatbots" and their uses, misuses, and threat profiles.
Personally, I think chatbots are an inane waste of time, and if it wasn't for the fact that I have to deal with them in my line of work (and in my personal life as well) I'd ignore them entirely and eschew doing business with organisations that deploy them. I'm particularly miffed at my bank and at Amtrak. For instance, Amtrak's web-site is so focused on AI and "making it easy" that train timetables [0] are no longer available and one has to go through the AI dance to even book a ticket. Fortunately I don't move around on the planet much any more and when I do it's usually only one change of trains, but the big trip my late ex- and I did in the 1990s would be completely impossible to book now; it simply could not be done using the AI and one cannot reach a human being. (That trip took me a week to lay out, using timetables and old-school techniques, was booked with a ticket-agent at a train station at an off-peak hour because it took 45 minutes of his time, and was one heck of a blast for two weeks as we rolled around the 48 states touching all four corners. It took ten different trains and had four layovers and eight connections [1]. Any modern attempt at AI would fail after the first connection.)
[0] Timetables, for gods' sake -- these used to be the bread-and-butter of the industry, and now you can't get them.
[1] I started in Boston, she in Worcester; we connected in Chicago, went to Seattle where we spent a day. I wanted to take the then experimental Spanish-made Talgo train whilst I was out in that part of the world, so we went from Seattle to Portland where we spent another night before getting on another one to San Francisco (back when it was still a nice city). From there, a very fast change-of-trains in Los Angeles where they held a train for us and hustled us across the tracks to get to the other one because walking the platforms would have taken too long. Then on to New Orleans where we spent 3 days (and I got mugged), then a fast change in Jacksonville, a trip up the east coast to DC, then a Metroliner from DC to New York, thence to Boston and back home to Worcester. Two weeks -- and the things you see are amazing!
