users have tried explaining it to you. Either you dont understand, or your not making an effort to read the additional material
we are not here to educate every user on the right use of Stack Exchange
a group of users can vote to say "we dont think this answers the question", for example
and if it doesnt, it will be deleted.
if a question is closed, users can flag the question for review to be reopened. The fact that it has been deleted tells me that nobody thought it was worth reopening the question for so long that it was deleted.
Alternativley, the original asker can chose to delete their question, but given your complete lack of compliance to answer simple requests for additional information or clarification, we can only assume that the question was of low quality, and enough users voted that removal was a better fit in regards to "quality control"
This is the important part you need to consider. It does not matter how long you have been around. It does not matter if you invented the Internet, you do not own the Internet. Once you publish your content, it is not necessarily yours.
I say this to clarify any misinterpretation you have; but any content you publish to Stack Exchange becomes common use license. You give Stack Exchange license to do whatever they want with it (in this case, let a bunch of other users agree to delete it). You should still receive credit if another user credits the answer in any work, but it is completely within the rights of the Stack Exchange network to edit or delete any or all of your questions or answers.
I'm going to point out another solution here, but you need to think very carefully about it. You seem to be upset about the fact that an answer you posted was deleted. The original question was not answered by your answer - a fact you clarify by telling us that the original question as too broad, so you answered the assumed "fixed up" version of the answer.
If you really think this answer is good quality, ask the specific question you answered, and self answer. That said, unless this really is a good quality post, do not be surprised if your met with more downvoting.
