Unless you are using this with something other than a computer like a PS3 or a phone or something (although any phone with decent internet capability should have some sort of auto correct that would be able to at least mask your mistakes to a degree), then you could type like that.
If you are using a computer, you really don't have any excuse to type poorly, at least try to make it look like you can :/ unless you are using something really outdated and old it should have a decent spell checker, is it so hard? Someone could type better on an iDevice, or even an Android lol!
Just cuz I wrote a lot doesn't mean I'm being mean or hard lol, just writing something detailed ;P
