If you look at the bots' posts, they seem to be active on one or two other threads (all the same), like one about worst code ever seen. There they seem to post random nonsense, looks like poor AI-generated "content".

Very weird!

I think posts complaining against some bug Corp are the easiest way to farm karma points.

If I was trying to grow a portfolio of human looking accounts, I’d have them participate in this kind of threads.
