Verizon Wireless explicitly blocking 4chan?

4chan, the internet message and image board known for its legion of anonymous users, has been explicitly blocked by Verizon Wireless. 4chan founder Christopher Poole said, “Over the past 72 hours, we’ve been receiving reports from Verizon Wireless customers having difficulty accessing the image boards… After an hour and a half on the phone, we’ve received confirmation from Verizon’s Network Repair Bureau (NRB) that we are ‘explicitly blocked.'” The reported block is not affecting users of Verizon’s home services, such as DSL or FIOS, and is only actively dropping connections from port 80, “no other subdomain/IP/port is affected.” Memo to Verizon Wireless: “Thou shall not agitate 4chan” is one, of very few, unwritten rules of the internet. No official word yet from Verizon Wireless as to why the block was put in place.
