I usually let bad spelling and grammar slide within reason. (The idea that native English speakers making more mistakes is totally true from what I've done/seen.) If I'm able to figure out what a person's saying and especially if I know they're not a native speaker, I work more to make sure I understood the intent of the phrasing, if it was vague or strange.
I'm not nearly as forgiving for native speakers/writers making the same mistakes repeatedly when I know that they know better. A "teh" or minor spelling error is nothing. Half the time, I'm making the same typing errors from trying to type too fast or because reading quickly, I just self-correct it in my head. buT wen I c some1 typin something thats rong just becuz they dont wanna type correctly, I get mad. That's not only a disservice to people who aren't native speakers, but also to everyone else who tries to read it.
If I know someone is a non-native speaker, I'll ask for clarification if they say something strange. Or, if I'm able to figure out a pattern of something they're saying that isn't quite correct, I'll try to find a gentle way of helping them improve their English. Maybe it'll come out as me using the particular phrase or syntax they're messing up, or maybe it'll be something blunt like "I think you mean _____?" But that would only be done when there's a clear loss of information in the sentence or a very distinct difference of meaning.
