Question about E-Mail?

[YDKKDY]

So, I was just posting on 4Chan's /v/ section about Dark Souls 2, and it was just asking what people thought, and I noticed one of the comments had my e-mail on it, and nothing else.

Out of curiosity, what can one do with an e-mail address and solely that? And if they CAN what can be done to prevent anything from happening

>actually posting your email in the email section
>being this new

All info connected to that email can be obtained.
The only thing you can do to prevent it from happening is shutting down the account.
