I used to have my email account hacked. They also hacked my Origin account, luckily I only had one game there (the account got banned for suspicious actitive). Now this is understandable. But for some reason, my email since then got used to sign up to universities in places like India and Singapore. Every week I get 1-2 emails from various branches of these universities. I don't understand why would anyone do that. I replied to some of them that they aren't reaching their intended recipient, but then I get emails from another department the next week.
