Well, if that's the case, they can easily switch to "show 'deleted' content" - removing your comments doesn't delete them from Reddit's DB.
That could have changed, sure, but nothing indicates that is the case.
You could also go the GDPR route and request all your data be deleted, if you are subject to that. They would be forced to comply with that request.
but if you overwrite first with garbage then delete that's what shows up in the dump
Do you think they are going to go through each of your comments individually to determine if it contains personal info or not? That requires actual time and effort, and as an individual user you or your comments are nowhere even remotely in the vicinity of important enough for that.
It’s far easier for them to take the loss and delete wholesale.
Do they do this? I don’t know, I haven’t done it. But it certainly could be argued that by them not doing this, they are not fully complying with the requirements of a GDPR deletion request.
It is 100% not the user’s responsibility to keep track of this information. That is explicitly a requirement of the provider and it is fully on them to ensure that a deletion request deletes all the personal data. If they didn’t tag it properly and can’t ensure that, then that is their problem to solve not yours.
Their value proposition is also not a single user’s data. It’s the entirety of the data set. One user’s data is nearly worthless, certainly not worth enough to have a human review it. Which was my point.
Another user said they tried the data dump GDPR request and the comments included deleted comments but only the edited version, so I guess this can be verified at least.
