The link above shows how STUPID you are. Period. People make fun of you for idiotic news items like the one in the link found there.
"Leetspeek" as you call it, is something everyone on the web MAKES FUN OF, not something we use on a daily basis. People who use "Leetspeek" are usually "noobs" who have no idea what they really are saying.
I'd like to inform you that I'm a software developer, a Security Operative (Thats a hacker that uses his/her talents in a way that benifits the person he/she is exploiting, by the way.), a Web Site designer, and also an avid Online FPS (First Person Shooter) player.
Your done, amx_rocket Kim.
