a user can't edit or even delete his/her own note...

Please enable a note editing and deleting.

I can’t take the risk to use them anymore, it’s just too risky.

thanks for your awesome work !

(currently using openstreetmap.fr

I found this about note deleting:

Why is it to risky for you to use OSM notes?
Can you give us an example?

If it is a risk for you, then DON’T create or edit them, thus no ris.

Agreed. If using notes is risky, then you’re probably using notes in a way that wasn’t intended.
