This seems to be a reoccurring problem. As someone with dyslexia myself I understand how easy it is to make mistakes. However, Stack Exchange is a site that is supposed to be professional and we seem to have a problem with some users consistently not bothering to use a basic spellchecker or proof read. It comes across as lazy and can damage the image of the site.
Down-voting doesn't seem to be the answer because once someone has edited the post it is no longer a reason for down-voting. It also comes across as fairly petty to down-vote and not fix the spelling yourself.
How do we go about solving this problem?
Note: I don't want to pick on anyone in particular, so I'm not providing examples; however we have users who should know better.
Note 2: I know that we have users who's primary language is not English, that doesn't mean they shouldn't be using a spellchecker.
tl;dr PLEASE use a spellchecker before you post
Since this wasn't known: If using chrome you can choose another language from the right click menu in a text editing area.
