Hello, I just received an email that my email was changed on my account(lakimens)
https://i.imgur.com/mJbyyUM.png

I haven't sent/posted a Bitcoin address, mainly because I don't use Bitcoin.
The address that is on my profile is for an altcoin, PRiVCY, I'm in an airdrop with it.
The previous address that was on my profile was my Ethereum address, I can also prove ownership of that.
Please help. My account has 390+ activity, more than a year of active posting. My account is locked right now, because I didn't want the hacker ruining it.
