How can I find posts which have been inactive for 6 months, as per the requirement for the Archaeologist badge? Is there some kind of search query or something?
Keep in mind that:
- SEDE data aren't exactly fresh, check the front page to see when they were last updated for each site,
- Editing en masse to get a badge is generally frowned up, especially if your edits are minor.
What I do is sort questions by activity and go to a random high-numbered page: if it had had activity within 6 monthes, if would be on a smaller-numbered page.
