Interesting. I didn’t know that about deleting comments. The web client on my instance has a delete button, but is there some kind of issue with that change not necessarily propagating to other instances?

It doesn’t bother me much personally since you never really can be sure that you deleted something from the internet. Even if reddit deletes a comment, you can possibly find it on an archive somewhere. Anything you toss onto the web should be something you’re comfortable with the world knowing.
