You could also use the account to damage their value for when they go public lol; the more comments you've made the better. You'll lose your account of course, so do it instead of deleting it.

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.

You could also redirect lemmy over here when you get the chance, and go upvote when other people do the same

At least for the time being, this is what I'm doing

same with my almost 3yr account
