Before I left Reddit, I used a plugin through the api to replace all of my comments with random gibberish and then delete them. Part of this was because (mandatory) fuck spez. But more importantly, it was to protect the anonymity of my account. After years of posting, there is likely enough personal information shared to potentially connect my Reddit habits to my online identity. I wasn’t planning on using Reddit again in the future on that account, but I left it open in order to maintain some security control over the account. I’m not really sure what to do at this point because I still consider it a security vector that’s a bit concerning. There’s no way I can manually edit and delete all of my content with the snail’s-pace reddit UI, and I have no ability to assure that my content will remain unavailable or at least not publicly displayed.
Yeah, it’s easy enough for reddit to detect rapid edits over a 1-day period and just undo all of them. That seems to be the case here. The edits I did manually were retained.
I used Power Delete Suite (javascript IIRC, via Firefox, year ago) to edit and delete, and mine are still gone. Not sure if it is still effective.
Reddit is probably less and less tolerant about edits and deletions, now that they’re full speed on selling our data. Still see plenty of deleted posts when I’m searching for things, which is… nice I guess (bittersweet).
