When looking at the questions list sorted by "active", I noticed a handful of older questions that popped up as modified. Usually when this happens it's a mod editing something, but these all showed as modified by 1 rep users. I clicked the questions to browse through the answers, comments, and edits, but saw no activity from the usernames stated on the question list. What's going on here? Am I just blind?
