Is it in the spirit of Stack Exchange to always make a sincere attempt to interpret the OP's intentions? I believe it is.
Precision is important in maths, and where questions are imprecise it will often be helpful to address that imprecision. However I frequently see answers or comments which pick some logical fallacy or inaccuracy within a question, then to declare the question answered on the basis of it, while making apparently minimal attempt to interpret what the OP intended.
I think it's important to interpret the OP's intentions and to address the question they intend to ask, rather than some technicality. We will all have seen perhaps the stupidest example of this, in which the next number in some sequence is proposed by some method which can generate infinitely many candidates all having equal claim.
I am in favour of such stupidity attracting a waterfall of downvotes from the community.
