Community Bot visits old questions and bumps them so that they can receive answers and hopefully have an accepted answer eventually.
However, many answers are old, and the OP sometimes hasn’t visited the site in years. It is therefore very unlikely they will see any new answer, let alone accept one.
Is there any way to reprogram Community Bot so that this kind of thing doesn’t happen anymore? I find it very annoying to see “dead” questions bumped by Community Bot…
