Nah, nsec is like the password for your Bitwarden or 1password, it is much more than just a password for an individual social media website. And if you have a lightining address it is like throwing your credit cards in the mix as well, you simply shouldn't use it on experimental clients (which is most of Nostr). Yes, reusing your Gmail password on vibecoded sites is bad, and this exactly why people shouldn't do it. The problem is the path not to do it in Nostr is broken.
TL;DR on deVine is that press and some big timer YouTube channels like Linus Tdch ztips got wind of it and a gazillion folks tried to join at once. Basically too many users / too heavy of a worjload for existing relay software and available relays. There was a room with the usual folks trying to provision relays for it (Gleason et all) but if you don't have the infrastructure for the normies to flock in all of the hype is wasted.
