I've done plenty of editing myself. Matter of fact, I'm an editor for a game manufacturer and an online magazine.
I have been paid a lot of money over the years for editing. I find it hard to believe that people who consistently write unintelligibly ( and you are not one of them) would not appreciate not sounding illiterate.
Nobody here pays you to edit their posts - or even asks you to do it for free - and even if they did, I'm sure that they would not ask you to ridicule them in the course of your editing tasks. Is that how you edited documents when you were paid for it? Made fun of the mistakes?
