The past 10 threads or so I've posted in, someone who is obviously a mod comes in and responds to my posts. I know it is a moderator because I've varied my typing style and subject matter, but the person who responds is always the same. I know moderators can view IP and also track all the posts from one IP.

Do the mods enjoy responding to users who post during the slow hours as a way to give off the impression to it's users that the site is more active?
