Thats what iv been saying 🤷‍♂️
If you want long term retention of your notes, run a relay and store your data. 
Else the relay could do a 30 day rolling period lol 
Old notes dont get the love they deserve anyways 🤣🤣🤣 

 The relay should retain frequently requested notes even if older. Also think about profile information and stuff that's longer-lived. 

 Profile metadata is tiny and i have backups.
