Be careful with OKCupid. I'd been using it on and off for a while and recently I got a notification saying that my email address on my account had been changed, then 2 minutes later, that my password had. You don't need to confirm anything to change the email on your account! Not even click an email link!

I was panicking

I was still receiving phone notifications despite not being to log into the app. I could see that messages were being sent and received but couldn't access my account. I believe that others are being scammed using my account

I quickly changed all other passwords and contacted OKC immediately. It's been a week now with no response. OKC have lost a paying customer for life
