Even if this was the internet, you are talking between humans, and usually when you are asking for a favour from another human, you have to use a language that the other will understand, and use it politely. honestly if this is how you behave when you are at a hostel, you will not live long in the cruel real world after you graduate, ecspecially when the world is getting more and more wired. You will communicate to other people everyday using the net and do you think they will not mind if you talk to them like this? I couldn't care less about your suspended account because if like this I totally agree with the ban, even if the person being banned is not you in the first place...

It's a certain habit that diffrenciate one another. Not all people will post alike, and certainly the habit of using space before fullstop are rare, which is why suspicion is aroused in the first place.
