I stayed away from the general popular subreddits that tend to populate /r/all preferring to stick to either hobbyist and tech related subs. I haven’t noticed much change when it comes to places like emulators or roms for example mainly going there to check the wiki and when myrient went down people backing it up and making Minerva.
So I guess if it is the general trash subs that the twitter crowd congregates along with news, the bots and stuff might be more apparent with it being about karma, trying to go viral, and manipulate what users see. But, the more resource oriented ones like Linux or buildapc still seem to be less affected with people there just trying to help out.

It worked for me. Comments never came back even years later and checking old comment links with gdpr files.
I think reddit has a limit on the amount of comments that can be viewed through your profile. So you won’t be able to delete everything in one go if you have thousands of comments.
You’ll have to do one run rewriting and then after deleting the comments it can. Then wait and do it a few days or a week later when the profiles repopulates it with the older batch of comments that weren’t available before.
