I wouldn’t say it’s a huge risk particularly, but good to know the tradeoffs. I host a NIP-05 “username” at stacker.news. Just be aware that if you tell people “you can reach me on nostr by looking for markola@nostrplebs.com” that could become a common way people look for you.

then some day, for whatever reason, you say something that gets a government upset - they could try to hassle nostrplebs.com to take down your NIP-05 mapping. Anyone you’re connected to on nostr already will continue to be connected since connections happen around the NPUB/cryptography, but new people looking for you might find it hard to find you 

 Awesome information.  Thank you again.
