I've had a few people making the exact same point, except very clearly stated as a threat.
It's also funny, because I chose my profile name just out of laziness, because I was still evaluating how nostr worked/behaved. I am very uninterested in improving the profile. I very much suspect that those threats were in part invited because of this.
So someone's trying to prove the point about how exposed I was and that I would be easy to track down, etc. And I'm like .. "sure, but I haven't bothered to hide".
I have made plenty of identifying comments, and if they only identified me in the last few weeks, I'm fairly sure they haven't been trying very hard. 😅😂😋
