They monetize your posts by serving ads next to them. If no one can see the content, it’s not monetized. The other thing is using them to train language models and such. That’s a little more abstract, and hard to account for.

Also, not sure if this is still a good way to do things, but there are tools to overwrite all your comments with useless text before deleting it. The thinking is that reddit and any third party websites aren’t going to bother storing multiple versions of a deleted comment.
