This was discussed before but that discussion is outdated.
Tags related to a specific person are generally bad. (This is not the same as specific topics named after a person, e.g. Galois theory is not really about Évariste Galois.) Some exceptions can still make sense, Paul Erdős is certainly a strong candidate for such an exception.
Whether or not this is a good idea, the tag erdos does exist with 31 questions and no usage guidance.
What should we do with it:
- Leave as is? (And explain how it should be used!)
- Rename to
erdos-problemsor similar? Perhaps multiple related tags?
- Eliminate the tag entirely?
