Like once a year, we usually clean-up old reviews in Gerrit.
Per policy, I've abandoned a lot of patches that were in merge conflict, or not reviewed, or WIP or not passing CI, older than 6 months.

If you want to check if one of your patches were abandoned: https://review.openstack.org/#/q/status:abandoned+owner:self
Please feel free to re-open it, and let me know if any trouble.

I'll also spend time on our Launchpad and also remove old bugs without any activity.
Thanks,
