I'm the user formerly known as EconomicsGuy/EconomicsGuy II/MartinDK/various sporadic and mostly infrequent IP edits for about a year or so prior to the summer of 2006. Thanks to my fanclub's passion for creating socks with my name in them "EconomicsGuy" is blacklisted as username which explains this name and why it wasn't technically possible to rename the old account back.
I'm not going to spend anymore time on this. This is really beyond absurd now. I'm stuck here dealing with a lunatic teenager while the administrators are busy creating buggy filters instead of helping me. This is ridiculous. I'm gone.
