I sometimes see a user repeat a question in multiple categories concurrently. Usually it's literally copied or retyped almost identically in each category. Is this allowed, and what's the best way for an answerer to deal with it?
1. Answer in one category and ignore the rest.
2. Answer in one category and then copy that answer over to the others.
3. Answer in one category and include links to that answer in others.
4. Report one of the questions and mention the others in the report.
5. Report each question individually.
