I believe so, yes. I’d try backing up notes you care about yourself using your own relay. Mines currently offline (thanks to my idiot landlord) but I had been using it for a few months and was able to keep all my notes

I'll need to look into running my own relay, thanks!
Notes being ephemeral makes nostr so much more inferior to twitter 😥
It’s all a trade off - either you have to trust someone else to store your data and manage your profile correctly, or you need to pay someone else to, or you need to do it yourself. Nostr definitely trends towards the latter two options.
