At least Bitmain did their part and basically emailed everybody who had their email leaked last year to warn them about these scam emails.
I got mine a few days ago and if you don't frequent the forums you could of easily fell for those types of scams since they appear legitmate.
Its not only the email, they have full names, addresses, phone number, VAT and all other information that bitmain have received. Probably got passwords also, and this leak did not happen last year.
