This is interesting. In Amethyst I see what I assume is my Tor exit IP. I'm definitely not in Luxembourg. Using nostrudel.ninja on the PC, I only see the letters. No IP at all. Also of note, I am NOT loading images by default in Amethyst and this shows up anyway.
@Vitor Pamplona Is this something that could be shown to a user during sign-up to let them know they need to take precautions? Maybe it would wake them up to the fact that they're visible.
