There are some questions on this site that meet the criteria for automatic deletion as
RemoveDeadQuestions, but aren't being deleted due to a bug, as they were migrated from another site.
Basically, there's a code optimization that prevents questions that were migrated from other sites and later closed from being deleted by these two Roomba scripts. This optimization is based on an assumption that was true at the time, but is no longer true due to recent feature changes, and isn't true on many older questions (more info in footnote). Taking a cursory look at these questions, most of them don't appear to be suitable additions to the site, but I'm opening this discussion here to provide a list of them and allow the community to discuss whether or not they should be deleted.
At the moment, this bug affects migrated questions closed prior to the concept of migration rejection being a thing. However, it also affects questions that were closed after June 2019 and after the migration stub on the origin site had been deleted.

And this Meta Super User question: What Stack Exchange site would be best for someone who's thinking about building their first PC?
The questions were taken from this query here. Note that the above list excludes questions that were already deleted since the database was last updated. Also, this is not a complete list: the query excludes questions closed as duplicates, so there are some more questions affected by this bug that are not in the list. Finally, it seems like this site is the most affected by this bug: there are more Super User questions in the list than from any other site.
More information: in the past, all questions that were migrated from other sites and later closed would be marked as "rejected migrations" and would thus be locked, and locked questions were excluded from the affected Roomba criteria. Because it was safe to assume that a closed question that was migrated from another site would also be locked, this code optimization was implemented, perhaps because querying for a question's locked status would take more time.
However, there are two caveats with this assumption: first, prior to 2012, migration rejection wasn't a thing: closing a migrated question wouldn't lock it. Second, in June 2019, the system was changed to no longer mark migrated questions as "rejected" if they were closed a long time after they were migrated. Both of these mean that closing migrated questions doesn't always lock them, and so we end up with the not-true assumption.
