Even as a visibility vote it's somewhat flawed. If you downvote everything that's wrong, then many people will miss out on corrections to commonly held misconceptions.

Power Delete Suite doesn't get everything. PDS goes through your New, Hot, Top & Controversial posts and deletes those - however your reddit profile doesn't display every comment there.
For example, I had many comments that were older than 3 months and <50 karma that were still left unchanged after running PDS to completion several times. In particular, replies I'd made to my top comments were still there, while the top comment itself had been deleted. I also had a couple comments in the gilded tab that it had missed.
The only way to get everything is to do a GDPR request to get all the comments with links in a CSV file. Apparently shreddit can take this to clear the comments, however the PDS dev shits on shreddit for requiring you to input your username and password. I haven't yet tried this, but I'm not aware of any other service that uses the GDPR CSV files.
For me it only exported the last set. The first few times it stalled with an error and I had to restart, but it had deleted comments and not given me a CSV of the ones so far.
In any case, PDS doesn't get everything, because not everything will be displayed on your profile. PDS goes through your New, Hot, Top & Controversial comments, anything that is not displayed in these lists will be missed. I ran it to completion and it said there was nothing left, but I had a couple gilded comments with <50 karma on the gilded tab that were still there, as well as many comment replies to the Top comments it had wiped.
The only way to get everything it seems is to do a GDPR request and use the links in the files you get.
PowerDeleteSuite doesn't get everything, though. PDS goes through your New, Hot, Top & Controversial comments as displayed on your profile. However, your profile doesn't display everything - many comments are too old or middling to low karma and don't show up, so running PDS won't get these.
The only way to get these comments is to do a GDPR request for everything on your account. This will give you a CSV file with links to each comment. Then, you need to feed this into software that does it for you. Apparently shreddit can take these files, however I've not tried it yet and the PDS developer shits on shreddit because it requires you to provide your login details.
I like to give it slightly wrong answers first, then right answers on the second attempt. Because they're blatantly using it to train AI (for free, without paying users for their work), I want to poison the data. The first one tells it that it's guess is wrong, the second one proves I know what I'm talking about - if you do everything wrong it will just discard your training data.
I went to a gas station that had facial recognition cameras. They cited theft, but also their "legitimate interest", using website cookie language - only there was no easily apparent way to object to their legitimate interest.
What we really need is legislation. The law needs to recognise that businesses cannot just steal data from people for free for their own profits - not to mention exploiting that data against the data subject.
If you build and sell a car, you have to pay for the nuts and bolts. You can't just take them and say "well, you wouldn't know how to build a car, and they only cost a tiny, tiny amount, so we don't need to pay you."
Personal data has value. So much value, the businesses that focus on collecting it are some of the wealthiest in the world. We are all being robbed.
Honestly I kind of wonder if this is all some kind of coordinated power grab to crack down on public spaces in the build up to 2024 elections.
