CyanicSpritewell if they have your account details or even just your e-mail they can get access to a shitload of other things related to you from your personal information, and if certain sites only let 1 person be logged into the account at one time they can hold you offline by ddosing your IP and then hack into your shit and you can't do shit about it unless you have a dynamic IP
this is somewhat misinformed. IPs are not exactly private information lol
your email address can lead to getting alot of personal info
