In a sense, you are correct, because there is no site rule requiring proper spelling and grammar. The only reason to do so is to be understood easier (because sometimes people can't understand what you're trying to say if you use incorrect spelling and grammar).
Note: This isn't the first time Bluydee has complained about the current state of the forums. This is his previous complaint thread.
Is this thread really necessary? No one is making you read the posts of people who can't spell. And remember, a large number of people on this site are teenagers or tweens. Teenagers can't spell for anything these days. With a few exceptions. In any case, could you please stop posting threads just to complain about something that doesn't help to advance the site?
