Don't, do this instead to fuck up their data and actively harm reddit's value when they go public.

Copied from there:

• [Choose 1/3] Open Zompist’s gen. Take off the line saying “ki|či”, and click “Generate”. You’ll get some random babble like “Bepe topioi kabi brete i kropra”, copy it somewhere.
• [Choose 2/3] Open https://sebpearce.com/bullshit/ to get an entire bullshit article
• [Choose 3/3] Open https://nonsense.x2d.org/ to get a bullshit sentence, i suggest getting a few ones.
• Open your Reddit profile and drag the button of Power Delete Suite to it.
• [Optional] Check the box saying “prepare local backup of items”, if you want to save your content elsewhere.
• Uncheck “remove comments”. You want to replace them with babble, not remove them.
• [Optional] uncheck “remove posts”. It depends if you post mostly self posts or if you post links/pics. Use your reasoning.
• Check “Edit comments / self posts”. It should open an input box for text; place the babble from Zompist’s gen there. Then click “process”.
• Just wait!
• [Optional] Click to download the backup of the items.

Let others know!

There have been some reports that Reddit is restoring deleted comments, so it's recommended that people overwrite their comments instead of deleting them.

Pardon my ignorance/laziness but I assume an archive exists? There is a wealth of knowledge there.

I liked Power Delete Suite for Reddit in the article, and used it to export a backup. Filed a GDPR request too.

As someone who tends to be almost too honest, to the point of it being a problem, I bet if you browsed my reddit comments, you could find exactly who I was just based on the vague details all added up. It's just kinda fkd up that I can't control what is left up for the future.

I want to leave my experience for others, as a trail of breadcrumbs for the advancement of mankind, but with so many malicious people, I am wary, and trying to be more mindfull of what I share.

I started going through and deleting certain comments, and leaving ones I find may be helpful in some vague way.

The issue I have with this is I've been banned from reddit. And power suit doesn't seem to work for me. Anyone else facing similar issue?

Please don't do this.
You can't achieve anything by being reckless & self-centred (Like how old are you, you can't process your trauma) all that will accomplish is more censorship on the internet aka more Repression/Suppression/Regression/Chaos/Divide/Disorder those are all variables that bring the worst out of people.

While they may lose content creators, the data can be used to build upon in the future for index/reference purposes.
