I check my Reddit profile every few months. My old posts are back again. Must be the third or fourth time since I left the platform.
Right now I’m running PowerDeleteSuite to purge my profile. I’m so tired of this garbage that I’m starting to lean towards sending a GDPR RTBF request just to stop having to redoing this every few months.
Most deletes on any sites are only going to put a flag on your comment like delete=“true” and just hide them. At best they get purged at some point or overwritten with new comments if database space gets low.
All that to say: any clean I do is always an edit first to make it nonsense. Then give it a day just to be safe and let the database propogate to any backups. Then delete.
