1) Chris doesn't read anything that doesn't immediately get his attention. Next time, tape Legos to your letter.
2) As other people have mentioned,
people in Sega do know Sonichu exists and they just run with it. CWC, in all of his glory, really isn't worth Sega's legal department.
3) A lot of us are angry about how Chris games the system, but as we've learned from agents around that area, there is no point in pursuing this avenue because out in Ruckersville, nobody really gives a fuck.
Really, most of Chris' life, people have just shrugged and let him slide on by. It's how he got through school, it's how he got his CADD degree, and that's how he lives now. He is a close-minded manchild that will curl up in a ball or use his patented deflection shield to avoid confrontation and/or responsibility. Try as you might, presenting to him to the most staunch facts that he needs to get his life into order, give him faultless logic and he won't care because it doesn't cater to his interests.
