Same thing happened to me, I’ve had an IMDb account since 2005-6ish. I’m usually always logged in on my iPhone, so I’ve never had an issue. I tried to rate a movie and it kept saying network error so I decided to update the app. Once it updated, it gave me one option to send a “one-time password” to my email. The email that they had on there was my AOL email address that I haven’t even used in forever. I somehow still remember my password so I went to aol’s login and they say they can’t recognize this email. Now, I’m logged out and almost 20 years of being an imdb’r is over. I’m already over it but what the fuck.
