I use a password manager with a very long randomly generated password for everything, so a hashed password leaking is essentially meaningless to me. Notifying me immediately so that I can change it ASAP is what matters.
The burner e-mail I use for stuff like this is listed in 25 other data breeches, too. I don't really care. Plex is amazing software.
I don't really understand the freak outs here.
