This depends on the social media site. With Twitter you can sign up for as many accounts using different email addresses. I was able to make a few using the same IP but different email addresses.
The same thing goes with Facebook. But I'm sure there is a threshold or limit to how many times you can create an account using the same IP.
You don't really need multiple accounts. With FB, you can create a page for your site under your personal account. If you're using a pen name that you would like associated with the page, then that's the time you create a separate account.
Hope that helps. Have a good day!
