This question is looking for answers or suggestions for us non-moderators. (Moderators have been seen to use their powers wisely in such situations.)
Very recently a somewhat vague question was asked and the OP resisted putting in clarifying information or a minimal working example and began to get downright nasty. (This particular question was put on hold.)
For this particular case I looked at the user's profile and saw a pattern of being argumentative after asking vague questions on other StackExchange forums. My comment was to repeat a previous comment about providing a MWE.
Other than either avoiding answering or attempting to be helpful are there some specific suggestions as to how to phrase responses to what appears to be a volatile OP?
