I used to be Tyfus, back in PoE days. I was a squatter and a punk in those days, and my first name is Titus.
Then I grew a little bit older, and then a lot older, and I found that I wanted a more acceptable, less 3dgy username for situations where that's more fitting.
Now I'm Standplaats (arch: a place a journalist is stationed in Dutch,) Kraków (where I live these days.) Only my really old accounts are still Tyfus or DeTyfus.
