I’d politely disagree my fren, one easy way of verifying nostr:npub12z8jsett3k6rv9fa2guau5p540qr2xuvjzkr8e432mglafjt99sqkw9zmx is real is by reaching out to her on social media accounts where her digital footprint extends years, IG & twitter.. I did this myself before I interacted with her, and I tend to do this with many other profiles asking for them to their reply on those socials to a dm or to add their nostr profile to their linktree links they have on those legacy social media profiles. 

One way of finding those profiles is if they’re using the same name on here as they were in their legacy social medias (good sign) then a google search of their username is all you need to find those accounts (IG,Twitter,etc), if not you can use google image search to drop in a picture they have here on nostr to see if you find a trace of it on the internet, most likely you’ll get a hit on 3/10 pictures, sometimes you won’t get any hits if they’re ai generated, then in that case you need a trained eye which not many posses. But they are so obvious if you spend more than an hour on the internet every single day of your life.
