Leetspeak, plz?

Interesting post from Zelda about different perception of the same word ("please") when it is spelled in English and Leetspeak. I was thinking about it and I admit of having similar perception as Zelda, maybe not as severe, but similar nonetheless. I am more inclined to help someone who speaks normal English rather then a person who uses Leetspeak addressing me. The problem is that I am not sure it is a good thing, I think, I should try to be more tolerant in this regard.
