Really Fucking Scary Internet Censorship / Net Neutrality Issues

The story so far:
Stephen: Hello!
Stephen: So, I encountered something strange this evening.
Stephen: I tried to go to a website, www.serials.ws
Valeria K: Hello, let me know how can I help you?
Stephen: and I recieved a message saying that the website could not be found
Stephen: not my ordinary browser message, but an earthlink page that told me the site couldn' be found
Stephen: I entered the same URL into a proxy website, like anonymizer
Stephen: and the webpage loaded fine
Stephen: responded to search queries, etc.
Stephen: So, clearly, the page is live and on the internet but earthlink will not let me access it.
Stephen: Which means that the page is 'censored' or blocked from me by earthlink
Valeria K: Please give me a moment while I go through the issue.
Stephen: I'd like to know if I can get taken off this filtering, and if I can't, I'd like to know what web pages are blocked/censored by earthlink.
