• It's worth it to fight to get your account back. I found out later that others in my address book suddenly had security issues with email, and social network sites. However, they never became as severe as my case. We think my hacker also tried to hack some of their accounts as well.
• If you ever get hacked, change passwords and security information on every other account you have on the internet. I did have some minor problems with breaches on a website I maintain, and strange blips on some other secured accounts, so I changed all passwords and security information on every account as quickly as I could. No troubles since then.
