Why don't they put in the community guidelines that all words must be spelled correctly?

And here's another thing too. Why is it that church people when they quote the "i before e except after c" rule, that they omit the syllabic clause that goes with it? Which states that the rule applies only to single syllables. And they ignore it, and this gives them the excuse to spell atheist athiest. And they come on here in droves spelling it athiest. I believe it is a sin, and I urge them to stop doing it on here. Which brings me back to my original question, Why doesn't Yahoo include requirement of correct spelling in the community guidelines? .
