I believe that your testing is a bit off -- as of yesterday Earthlink was
blocking social media, primarily (or entirely) through local DNS
manipulation. This could account for the difference of your experience, and
why users with foreign DNSs can still browse without other tools.

Yesterday I ran Alexa's top 100k through a DNS resolver in country and
found aberrant results for the following domains:

facebook.com
youtube.com
twitter.com
xnxx.com
whatsapp.com
viber.com
youtu.be
hanein.info


The returned address for these domains briefly attributed the filtering to
the security situation in country, until it was modified within a couple of
hours: https://twitter.com/CDA/status/477488959044321280

If you have an Earthlink VPN, it might be interesting to see if you can
browse to the RFC1918 address 192.168.222.66, I think it's the block page
for that ISP.

(Bonus points for a sending the domain of a porn site to Libtech)
