No, it if offical at&t is blocking 4chan. I am wondering if they know what they are doing, seeing as Mr. Randall Stephenson, CEO of AT&T has had all of his personal information plastered all over the internet already.

Here's more of his contact information:  {Edited for privacy.}

I have filtered out most of the information on it, but this was taken from the /b/ board on 4chan, if you have not seen how they react when scinontoly acted out, what makes you think they will treat at&t any different?

Some more info on how they are combating at&t

THINGS THAT HELP
-Spreading the word to EVERYONE that AT&T is banning sites
-Using hotbutton words like "censorship" and "net neutrality" and "unconstitutional"
-remembering that only 0.1% of internet users care about /b/, and "DEY TOOKUR /B/" will barely stir up anyone
-Sidewalk chalk
-Keeping Anonymous updated thru dramatica, insurgen.info, partyvan.info, Digg, etc. etc.

THINGS THAT DONT HELP
-DDOS
-LOIC
-Ordering Pizzas
-Prank calling (were you really thinking about doing it to the CEO of the biggest phone company in history? derp)

Sad to say most will not follow this and if the ban is not lifted I am willing to bet DDos, Loic and probably ordering of pizzas will happen, the prank calls will happen if we tell them to are not that is just a given.

clearly I hope you love that pizza, since there is about 20 heading that way right now Mr. Randall Stephenson.

I must note, I am doing nothing that is listed above, I have comcast for a internet provider, I am just sitting by laughing at all the stuff that is going to happen to at&t. 

Only way to stop it is to lift the ban on the website.
