Somehow, a (very probably scam) app got into the top of search results, and I inadvertently installed it, and gave it my login information.
I managed to login via official means, and change the password. Thankfully, I never ever added any kind of payment information like credit cards or such, and I don't think they could get anything useful from the account, or send messages on my behalf.
