Who the hell would waste their time typing in numbers?
Leet was originally created by hackers to let them communicate even when people were following their conversations online. The numbers and symbols and such confused any investigators trying to track them down. Eventually it moved into games and really isn't used anymore by hackers. Now its more of a tounge in cheek thing.
Any of you who play online games, probably on PC, will probably know what it is.
From that link:
This style of speaking has now been abandoned by a number of the original users,
Leetspeak is not popular among all hackers, and nowadays is most commonly used in an ironic manner to represent immaturity or to annoy people.
Many consider it a pointless affectation
I don't think I need to read any more.
Yes doctor, I am sick. Sick of those who are spineless. Sick of those who feel self-entitled. Sick of those who are hypocrites. Yes doctor, an army is forming. Yes doctor, there will be a war. Yes doctor, there will be blood.....
