As I've said here, I believe it is much more useful to characterize a publisher (or conference, university, etc) than ask about it by name.
Consider the question "Is a university that grants me a PhD for $1000 and a copy of my unpublished book fake?", which has a great, general answer that someone put some non-trivial effort into. There are dozens of diploma mills out there. If this question is asked dozens of times (once for each diploma mill, by name), either (a) they won't all get such great answers, or (b) a lot of effort will be duplicated providing essentially the same answer to dozens of questions.
So I am in favor of the following policy for questions that ask about reputability of X:
- If there's an existing question about a Y which has essentially the same characteristics of X (for purposes of the question), close as a duplicate1. Indicate to the OP in a comment that while the name is different, X and Y have the same relevant characteristics and so the answers still apply.
- else, edit the question to ask about something with the characteristics of X, not just X itself.
1 I prefer closing as a duplicate over closing as 'too localized' in this situation. Duplicate questions are not usually deleted. So it's still searchable by name (i.e. will still show up in Google results for "Is X a scam?"), and also, can be reopened by the community if, in the future, somebody decides that X is different from Y in a way that affects the answer to the question.
