Yeah. Nuked.
If so, check out this poster. This is also the work of a chatbot, and I think no one will have any doubts. I reported his posts, but he was left Unhandled, despite the fact that several other similar posts were safely deleted.
Should we report users whose posts clearly look like the work of a chat machine?
Yes, please do, though obviously they will need a little more verification so might not get handled straight away. It's probably going to get out of hand fast with these issues now. Personally I think it might be wise to look into disabling sigs on all new users/lower ranks until people have earned the right to have one through acquiring a large amount of merit.
