Is it because it broadcasts your note to npubs you don‘t follow?

Its because its spammy and is a good way for your notes to be not written due to write rate limiting
same way email became a handful of large providers.
I did not know that. Thanks for the info!
Does this mean that this tool (nostrsync live) is no good either? Since it broadcasts all your notes to all major relays, when you do a backup with it?
