Closing MRs when someone is removed from the `gitlab-org`?

@rymai and I were discussing if Community contribution label should be added to MRs that were opened by GitLab team members and are still open when they leave the company (and thus removed from gitlab-org). Currently, we don't add the label after people leave the company as @markglenfletcher added a logic for the label to be added only for MRs that were created in the past 4 days

I think in most cases, work on these MRs do not continue and can be closed. And if the work needs to continue, another GitLab team member can open a new MR to move the work forward. What are people's thoughts on auto-closing these MRs and generate a (weekly?) report that can be sent to PMs/EMs?

When you look at stale/inactive MRs (e.g. that were opened ~12 months ago), sometimes it's not obvious if the submitter was part of gitlab-org when the MR was created.
