This is interesting:

“When "Incognito” is turned on, your current profile name and image are NOT shared with your new contacts. It allows connections with other people without any shared data – when you make new connections or join groups via a link a new random profile name will be generated for each contact or group.

This page allows you to create a long term address that can be used by other people to connect with you. Unlike 1-time invitation links, these addresses can be used many times, that makes them good to share online, e.g. on other social media platforms.” nostr:note1zk5f6y07zzfesv3ujwky0662re5x83xla4juw4mx3aacfgw70fgsfnxhar
