So, I got bored and started to Google my name and found someone named “Jerakeen” (my name, Jeralkeen, without an “L”). I was amazed and searched “Jerakeen”. She/He/It has two(2) websites: FanFiction By Jerakeen and jerakeen.org.
This is exactly why I abandoned the old nick. I'm a nerd / computer programmer. The other jerakeen writes gay fanfic. Not an area where I want confusion, thank you very much. Alarmingly, they seem to own the google results now.
Take this as an important lesson, fellow nerds - it doesn't matter if you've used a particular nick for 10+ years. Normal people use the internet now, and they can DESTROY YOU.
