DrStalker is based on my real surname and would be very easy to trace to my real name/employment details/the city I'm in with a few minutes of effort. I'm sure someone with a bit more time could get a lot more information than that. This helps remind me that everything online can be traced back to me, so don't be an asshole in situations where you wouldn't be an asshole face to face.

I settled on this after going through lots of different nicknames in the 90s, when the internet was a very different place.
