How do you get the password to YOUR nick on IRC when you registered it but somehow the password changed and now you can't use it? And the email for recovery is changed, too? And you're being ghosted a lot by the person who has the password to your name?
If the email is changed and the password is changed, it means that something of yours was messed with by another person for one reason or another. With both changed, not sure there is a way to recover that doesn't involve contacting the place you registered your nick with.
Nevermind, turns out the person who had the password gave the nick back. But they had no idea who put /kill on it. They didn't, and apparently they were the only one with the pass.
