Just the email, nothing too bad. It's happened, you may have been doxxed, already, and now is time to react. An email doxing though. Not too bad. Unless it's your work, your personal, your email, has your name in it. Then it's bad, or it could be. But it's happened, and now is the time to respond. Bing bing bing. Clicking and typing, preparing, signing up for porn sites with that email, saying it got hacked, no one cam judge you, no one, a human, just a human, you're, it's nothing. Anyone. Anyone.
Here's a list. Check yourself if you're on it.
