• It won’t pass congress: Okay, granted our current Representatives are only slightly more competent then 5 year olds… they still understand (at least by this point) that SOPA has way too much opposition to be allowed to pass quietly. It’s already been declared (after Egypt) that “if your government shuts down the internet, you shut down your government.” With the occupy movement already causing lots of head aches, its very unlikely congress will want to stir up more protests.
   
• It wouldn’t work, and would eventually be shut down/stalled: The people who would actually be willing to implement such technology are much dumber then the ones who will be looking to exploit or bypass it. I’m amazed the government/media industry was even able to find IT folk ignorant enough to think something like this could be made to work. In the unlikely event SOPA is passed and implemented, it will be targeted from the very beginning by malicious hackers who will be looking for a way to shut it down or exploit it in some way. You can expect “anonymous” to attack such a system constantly, but even if it could tolerate such an attack, there will still be a huge number of much more intelligent hacker folk, most of which have more knowledge then the entire IT staff of the RIAA and MPAA combined.

• Even if it does happen, it wont be effective: Already someone has released a firefox plugin that will use international DNS servers to resolve addresses, rather then an american run one. An average computer user would be able to find ways around the filter (just as users in china find ways to get past the filters there). Hackers, will have no trouble at all using one of the many methods currently established to bypass such filtering. 

• The US Government (ICE) is already capable of and has used this kind of censorship: Its not the same methods as whats layed out by SOPA, but ICE has already seized hundreds of domains without any kind of due process. At least one such domain was later released to its rightful, after holding it for a year without any cause or proof of wrong doing (http://arstechnica.com/tech-policy/news/2011/12/ice-admits-months-long-seizure-of-music-blog-was-a-mistake.ars). Edit: Here’s another wrongfully seized domain: http://virtualhackers.net/.
   
  
• IP Addresses will still resolve properly. Remember back before you had a cell phone that held all your contact numbers for you, and you actually had to remember them (or write them down on paper)? Well that might seem like a pain these days, but its really the worst thing you might have to look forward to if sopa passes. People have already preemptively started keeping lists of the IP’s for sites they frequent that might be taken down. While this method isnt the most sophisticated, it works all the same. With SOPA in place, lists of addresses would be circulated among those who wanted to access such materials.

• It actually makes online piracy and crime easier: Assuming the system is put in place and appearing to work, a much less watchful eye will be given to things currently targeted by anti-piracy campaigns. Lawsuits like the ones from the RIAA and MPAA will be a thing of the past (except in extreamly rare cases), because the resources will be focused elsewhere.
• Why its

As many people have noticed Comcast has started to ban diagnostic modems running the d10/d11_walledgarden.cm config. If you believe this has happened to you, read below:

Symptoms:

• Signal levels are within the DOCSIS specifications and you are a subscriber to Comcast services and are on a unfiltered line and receive the errors below:
• Your subscriber modem works fine, but your diagnostic modem receives the following errors:
• No Ranging Response received - T3 time-out
• DHCP timeouts (DHCPc: No valid offers to select; need to send discover again.) continually and your modem never receives a HFC IP.

• Change your HFC MAC to a random but valid MAC address and enable BPI+ Bypass.
• A valid subscriber HFC MAC and BPI+ Bypass or cloned BPI certificates.
• Flash a 2MB dump (or just the nvdump) that has matching MAC and certificates that are not banned on your CMTS.
• Change your HFC mac to a random but valid (or just change 2 of the any but the first two octets hex) and set BPI to disabled or 1.0 and use the config: d10_m_sb5100_showcase_c01.cm this method will only last until docsis 1.0 is removed. it already is in some areas.
