I also recently made a browser extension because those two tools are outdated / hard to use: https://chrome.google.com/webstore/detail/bulk-delete-reddit...

Let me know if you try it! Still developing and would love feedback.

ares isn't on the firefox store anymore and PowerDeleteSuite gets responses that are "success: false" 99% of the time because it doesn't fit the throttling they have very well so it leaves huge gaps of un-edited posts in your history

Ares can be installed manually but the building process has a few holes, namely, you need to rollback your node version to 13.14.0 and it's not mentioned in the readme. You can use nvm to do that (nvm install 13.14.0 && nvm use 13.14.0), then the normal stuff (npm install && npm run build)

I looked for a reddit history editor a while back and found those two as well, it's sad it's hard to make them work unless your account happens to have the throttle it expects

It’s pretty simple to do yourself. Last time I did this, I injected jQuery and wrote a few lines to delete a comment, wait a few seconds, delete another… then you reload the page and do it again. I would imagine that most HN members could do that fairly easily.
