the account that posted it called "milly" with the cat ears and anime girl is my account on discord lmao, my twitter handle is the same as the username on this website, and the account in that screenshot is my account. if you're in the discord you can click on my profile and see that multiple of the accounts that are linked to it are called plarpedbees.
i did post this in the goldpro discord server before anywhere else, and it was a little frustrating at first because the server owner didn't even believe it was a legit email. i had to download the .eml file to prove it 
so far, i'm one of 3 confirmed to have received it, in that discord.
