I don't believe there's anything sinister going on there Simon, that initial name is what appears in its profile page URL. I've seen it a few times before so I wonder if it is caused by the sheer number of usernames there are now, but I don't know.
True. Mine is the same way, actually. In the URL, it appears as simontya8u, but that’s never ever used in activity or any posts, always my actual username. But that’s not the case for the bot here.

HamdenPro:Perhaps, this bot was created by WGT. I noticed that it posted a week after "joining". Most bots post the same day.
Honestly, Steff, I thought the same thing, but the problem is... I keep asking myself... what would the company even gain from making a bot like this?? I just don’t see the point personally.
