What are the rules?

Thank u v.much...
Did I made something like that? and that made a question I read before and ans. erased! I don't think I did that, but may b I didn't concentrate? even that I don't mean others c the word not the heart so what Mrs.?or if others did so in the same Q. that'll cause that erasing?
with sorry to annoy,,,but this thing is bothering me and I wish to know? pardon,,,

If questions are removed, all answers and comments go with it. That doesn't mean the person answering or commenting did anything wrong.

I don't recall a question of yours being removed and you are correct, the people on this end can only see the words, we have no way to accurately know the intent. I'm sure there have been cases where questions have been taken out unfairly. If you ask the question as clearly as you can, that helps to insure that it will not be misunderstood.

It is not mine, :( it just happened that I read it& gave an answer for i...
I do conc. on my Q. and I won't say wrongly! I don't have other then normal Q. , but the ans. z what may contain what may be misunderstood..

The unclear Q that may b wrong 2 b asked once anyone read it,,,I also think that they should b erased, or who read it 'll think this wrong z acceptable in this website making wrong thought about it,,but what I answered stayed 1 day & this made me ask what is the problem is it my ans.or there would b another who ans. & said wrong..
really thank u and sorry 2 bother in some detail unnecessary,may b I should ask other Q. that r helpful and useful, but this is something that I care about more then knowledge which can b even in library then the understanding of a fault, done...(no way to keep correct once u don't know what is it, or no one tell u about it )
thank u v.v.much ^-^
