a great deal of discussion on this very topic is taking place in the thread at

As of the latest revision a.k.a. 'markup', the SOPA law's provisions to block access to websites does NOT apply to US based websites. It only applies to 'foreign' websites accessing the USA. Well that's not entirely true, because it also appears to cover US based websites that have 'foreign' content.
In the first case, a claim of copyright violation against a non-US based website can result in US internet backbone service providers, US online credit card processors, US search engines, etc. being forced to 'block' the foreign website's domain / stop doing business with the foreign website. This would probably affect certain webcam hosts like StreamMate, since they are based in Cyprus. If a copyright violation claim were lodged against StreamMate, for example, US based camgirls could no longer access StreamMate's streaming video server to transmit their webcam stream. And while StreamMate could still operate with non-US camgirls, they would NOT be able to access US webcam customers.
Where 'foreign' content on a US based website is concerned, the same SOPA 'blocking' can also be implemented ... but it happens via the authority of the US Immigration and Customs Service. After receiving a complaint that a US webcam host site is retransmitting copyright violating content from a non-US source, US ICE is able to use their authority to 'seize property' to stop it ... in this case by 'seizing' the domain name of the US webcam host. ( and pointing it to a page that simply says that ICE has 'shut down' the website ).
It is noteworthy that certain provisions of the bill STRONGLY motivate US internet backbone providers, US online credit card processors, US search engines to 'voluntarily' act to 'block' websites upon the receipt of a first complaint. The reason for this is that the latest version of the SOPA bill grants 'immunity' to these entities if they act voluntarily. That 'immunity' will also extend to lawsuits brought by the 'blocked' websites for financial damages etc. Without 'immunity', those entities are potentially liable to be sued by Hollywood studios, US record companies etc. for the financial losses they are experiencing as the result of those entities 'facilitating' the ongoing copyright violations. Note that in 'real world' terms, no legal proof of actual copyright violation is necessary for these entities to 'voluntarily' take action to block a website for which a complaint was lodged. Also note that, if 'blocked' by the 'voluntary' actions of these entities, the 'immunity' granted under SOPA for voluntary action essentially leaves 'blocked' foreign based websites with no formal legal recourse to attempt to have the 'block' removed ( like requiring legal proof that a copyright violation actually took place ).
The industry scuttlebut I hear from business acquaintances is that, while the stated purpose of SOPA is to protect copyrighted material owned by Hollywood studios, US record companies, US mainstream adult video producers etc. ( and thus increase their profitability ), the unstated purpose is to legally 'protect' US internet businesses from foreign competition.
This is NOT about blocking 'adult content'. It is about blocking non-US based businesses ( i.e. webcam hosts based in foreign countries ), as well as blocking non-US based workers ( i.e. foreign camgirls working through US based webcam hosts ), from accessing US ( webcam ) customer dollars !
When I asked, one business acquaintance pointed out that the likely effect of SOPA will be much the same from a 'market' standpoint as the law passed to restrict importation of foreign manufactured ethanol into the USA, the law that restricts the importation of ( totally ) foreign manufactured vehicles into the USA etc.
I would also add that my business acquaintances are almost certain that the SOPA bill will pass and be signed into law very soon. The major supporters i.e. Hollywood, US record companies, labor unions covering workers in those industries, etc. are also all major political campaign contributors !!! In fact, the final SOPA hearing has been rescheduled for next Wednesday, in the hopes that testimony from opponents can be kept to a minimum due to the proximity to the Christmas holiday. And this final SOPA hearing will be the 'last chance' to change the provisions of the SOPA bill. So by the latter part of next week we'll find out exactly what sort of provisions will be included when the SOPA bill is voted on and potentially signed into law.
