I've run Power Delete Suite a few times, however it looks like it doesn't delete everything. For me, comments that are older than a few months don't show up in /[user]/?sort=new, and similarly there is a limit to comments displayed under hot, top or controversial. The script also missed my comments in /[user]/gilded - it looks like it only runs on the 4 sorting methods in /[user]/overview.
Basically, my comments that are more than a few months old and have less than ~50 karma (which is the vast majority of them over the years) are invisible on my reddit profile, and thus unavailable to PDS.
However, I did a GDPR data request from reddit beforehand, so I have csv files of every comment, including links. I feel like it should be pretty straightforward to make a script to read the csv, open the links and edit each comment, in much the same way that PSD does. Only I'm not quite up to the task.
Does anyone here know of such a script that's already been made, or know of anyone who would be up for making it? I feel like it's not just me in this boat, and in fact many people might think all their comments have been deleted when they aren't.
