I would check again to make sure

I have a feeling they're going to undelete any activity within the past or next few weeks. I personally am leaving Reddit alone for now. In another two or three weeks (months?), I plan to go in and delete all my old posts slowly over time (or replace with some statement about moving to kbin social).

I'll likely write a manual automated script to parse through and overwrite over a decade's worth of comments/postings to ensure it's erased/gone.

But for now I've blocked the reddit domains from my router so I don't accidentally visit the site and ensure they see zero traffic from my IP address
