Well, have you signed up for any crapcoin ICO campaigns or giveaways? It's a known fact that there's several of those that have been collecting and selling email addresses and most of them are all types of shadiness and scam-bastardry. Was it an address unique to this forum? Are you sure you didn't sign up to any other crypto related sites with it?
Yeah the address isn't used on any other site associated with Crypto, I am 100% sure the breach was from here. i have not signed up to any other forums or even exchanges with my hotmail account. I have a dedicated email address I use for Crypto related sites like exchanges and haven't signed up to any ICO sites even with that address.
I am quite careful with my emails, which is why I am asking about this recent mail that was sent to me.
As far as I can tell, the hack must have happened in the last 6 months.
