when the relay is auth-requqired and these types of events are made private like DMs you can update them with reader tags to allow other users also on the relay to use the data

but for public relays without these you'd want them to be encrypted AND ideally protected from unauthed users seeing them but i don't think there is another relay that actually does this other than #realy - because i'm not one of the kool (-aid drinking) kids of course... but some of y'alls get what i'm doing
