It's worth noting that often, the email can be correlated with other breaches to get your real name. People can do that relatively easily on osint websites. I wasn't terribly pleased when I found my teenage furaffinity account show up in an identity theft monitoring app. Other people have turned up in breaches of far more objectionable websites.

If your email provider offers email aliases, you should really get familiar with how to use them, and use a unique email alias per website.

At this point it’s all public. Everything you do on the internet is or will be public.

I was also in the furaffinity leak lol. Though ultimately everyone is in so many leaks it won’t even matter. Unless you have committed some kind of crime, having possibly embarrassing personal details leaked is the reality for everyone right now.
