I compartmentalize all my email addresses to keep track of companies that sell personal information or potential leaks like the ones I am detecting right now.

I register each website with an unique email address, and if if such email receives any spam unrelated to the company it was used for, it has been sold or hacked.

After Bitcointalk got hacked in 2015 I changed my email address for this forum. The Phishing attempt didnt come to my new address, but to the leaked one. Therefore it is confirmed that these guys are using the leaked DB from the 2015 hack and it is not from a more recent hack.
