Take a chill pill. Yes it seems ridiculous, but if you're not logged in there is an "ask the community" box that asks for a title and is pre-populated with "Hello," in the question box. Its not like they are doing it just to annoy you.
This is an international forum, most of the world does not speak English as a first language, and these are peoples first posts here, possibly on any forum ever, from a not very informative box with zero instructions, just two titles not in their language. For all you know they think the title box is the question box and there's not room because they normally see labels underneath a box. Or are thinking of it like an IM and waiting for someone to engage them. Or don't actually know enough about computers to know what they are trying to ask. How would you like your grandmother's intelligence questioned because she made a mistake asking for help?
Yes I'm given to a sarcastic "goodbye" response now and then, although I'm more hoping they'll see the issue when they pull up the thread and provide info, but deriding entire countries/groups of people communication skills and intelligence because YOU don't understand them and can't give the benefit of the doubt is not civil behavior. I always wondered why we were forced to take "cultural understanding" for engineering when we are all just people, but I see some need it.
As an aside your sentence structure, paragraphs, punctuation, and grammar are not exactly stellar. I'd guess English isn't your first language either. Not that it bothers me. I enjoy irony.
