Could've sworn. I posted on this topic before...
Specifically my original username was "HYPER SONILDOW", or without the space in between. I can't recall correctly. It's a horrendous and n00bish username I know, but I can't blame my infancy stage for believing that it was cool at the time. I do remember the origin on where it came from. At the time, Sonic the Hedgehog (2006) had came out, and I was one of those that thought the game was amazing, so what I was beginning to think was "what if I take Sonic, Shadow, and Silver's name to make a cool name, and throw in Hyper just to make it sound cooler" and out came the name "Sonildow" which obviously you already know. For some unknown reason I did it in all caps to make my name isolated, and outstand the other usernames on the messageboard, because I thought it was just the coolest name anyone could ever think of. turns out later to myself...HELL no.
This is when my generic username "Thompson" comes in.
After I saw everyone starting to alternate their names, I private messaged Rob, and well, I attempted to make a a few various generic names. I forgot what they were... They never were accepted, and I thought "screw it" im going to just try in Mr. Thompson. Thompson's my last name for anyone that didn't know. Few days later, Rob entered my name wrong on purpose I believe, and put Thompson instead. Sounds boring... but, I've grown to like it alot, and I kind of love whenever other users announce my name in a post. <3 Just thought I could share my story...
