Maybe a spreadsheet of time-wasting npubs would be better
This would include people who dodge questions, but also people who ask fake questions just to make you waste time rephrasing yourself, for example
That's a much more useful dataset than one narrowed down to question-dodging, but also harder to organize as a spreadsheet
This is the kind of thing a robust tagging system would be really good for - if you just add a tag to a user's profile every time they waste their time, you would be able to see which npubs have the most time-waste tags from your followers. And of course these should be attached to each instance of it happening, to make it easier to identify honest vs dishonest taggers
