@rosborne979,
Yes, bot is a shortening of robot. There has been a spate of "new members" who all use a slightly varied boilerplate first post, and European sounding names which very likely have come from a name generator. William Henry here is one of those. None of them ever respond again to their initial thread, and most of them never post again. Among those which do start other threads, it seems that they never respond to the threads they have started. Most people who are familiar with the phenomenon believe that they are bots--automated accounts which use a variation on various texts in the attempt to appear to be a living, breathing human who is posting. I think it's from China, and it may be an extended experiment to see if it is possible to create bots which will be mistaken for humans. So far, i'd say it's been a miserable failure.
