Before you start note-ing on #nostr - know that there is no guarantee of deletion .. your content , as well as your account .. #nostr apps make best effort - but it is that - best efforts basis !
It is all fine - I guess - if you are using #nostr as an anonymous (psudonymous) channel .. but if you are attaching your real identity - be careful in what you post - you permanently own your record - digitally signed !
This is not an alarm because I think it is a good thing - makes you think twice before you make a note - free speech always comes with accountability 😜 ..
