I'm less black and white about it now. nostr:npub1gvy07gxw6uu8rd57mz72mg4q2x7r5ptpp5gc832dv768e58hqd0q5nyn0t reminded me of a potential accidental image self dox. Thankfully I was able to get it removed from imgur for that. 

Even if it is difficult, if not impossible to guarantee deletion across multiple relays - I'm okay with that illusion of deleting egregious typos and attempting to replace with a better version.

Also, I've heard a rumor that lots of dm's can slow/crash a client (Amethyst in particular), so deleting to remove them is also something I'm okay with just to improve client stability. This is definitely a practice I engage with because I occasionally self DM to check if my note renders correctly.

Again though, for me its not so black and white and I understand both sides.
