I've seen this happen many times: A question will show "Community Bot modified 48 mins ago" on the index page, but when I go there I can't find any evidence of an edit to the question. All the index entry does is waste the user's time.
Is there any reason why some sort of info about the edit can't be made visible, and, if not, can we skip the useless index entry?
I asked about the removal of the "Bumped to the homepage by Community" banner in 2019 and they said no, they won't add it back. (See Where's the bump notice?) The bump notice is now in the timeline (example). A separate request to change "modified by Community" to use some other verb was also declined.
Looking at these questions is not supposed to waste your time — you're supposed to evaluate the answers and see if any deserve upvotes or downvotes. Votes on the answers will cause the question to be ineligible for further bumps.
Alternatively, you can use a search to only see the newest questions and answers.
For the sake of completeness I'll note there are some other reasons that a post might appear to be bumped by Community (namely, anonymous edits and activity from deleted/destroyed users). As a user with 10k+ rep, you can click on "modified [date]" at the top and be taken to the post with the last activity even if it's a deleted answer. Lower rep users can't really do much when there's a deleted answer, but they will still see the post being bumped since everyone sees the same homepage.
