I just spent all day today fighting with reddit, trying to get all my comments deleted/overwritten: https://kbin.social/m/RedditMigration/t/45417/Anyone-have-experience-with-deleting-comments-to-see-older-comments#entry-comment-190482
It's not just me, someone else reported the same, though using a different tool: https://kbin.social/m/RedditMigration/t/46805/Strange-phenomenon-while-deleting-my-comments
Basically, reddit has the most ridiculous api ever! A 1000 limit on viewing .. well basically anything. Try to go further back, and you can't.
The tools and scripts and websites we are using to delete, they are hitting that limit and can't go past it. My own reddit is only 5 years old and I hit this. I imagine that many folks where, the ex-redditors who had 12, 17 year old accounts, you probably didn't get everything on your way out.
Unless of course, you had a data retrieval request made to reddit, and reddit responded with your data. Only then are tools like shreddit and websites like shreddit.com able to completely wipe out your history. Or else you knew about this somehow already and used an external manager like eternity - https://github.com/jc9108/eternity - to save a copy of your posts before they got lost to the 1k limit.
Worst of all, it's explained that deleting items does not rebuild the list - so you can't see the older stuff by deleting newer stuff.
I'm hoping that private/public transition is an exception to this and it'll rebuild my lists when that happens. Maybe then I can go far back enough to delete everything.
Edit: Nope, someone confirmed in a comment below that this doesn't happen.
Also looks like pushshift is not an option, as pushshift was shut down last month, https://old.reddit.com/r/pushshift/comments/13mhuzq/api_has_been_taken_down/ - and under the new deal, regular users won't be able to use it when it opens up for business again, only approved moderators can (and likely only for approved reasons) if i'm understanding https://old.reddit.com/r/pushshift/comments/13w6j20/advancing_communityled_moderation_an_update_on/ correctly.
This was my plan as well, but I'm worried that the request will only be answered after July 1st, and maybe the tools will break with the API changes that happen then.
Will that affect even small-time users like us who hardly ever use the API? That would kill things like the conversionbot, remindme, etc too.
Say we then have 33 comments left to redact. Or 22 comments, 11 posts. One api call to retrieve info about it (including content), one api call to edit to overwrite, and one api call to delete. That puts us at 99 api calls.
I guess someone could modify shreddit so that when running on the archive, it does 100 api calls max, then sleeps whatever time period required, then wakes up with the limit reset. Might work, just take longer. But we'll have to see.
