I find a lot of posts containing incorrect spelling. If one puts aside regional differences and typos, it still leaves a lot of words that are either misused or spelt incorrectly. This reduces the quality of a post, and can be the reason a post is skipped over by a merit awarder. This is because it shows a lack of care, and disrespect for other members reading the thread.
I got your point body. But not everyone here is well-spoken or can write English properly. Even in your post has an error in grammar, so you cannot tell everyone here that posting wrong English will reduce their quality post. They are just trying their best that they could to engaged and ask people to help to learn here and be better.
