The U.S. Senate is debating a proposal called COICA (Combating Online Infringement and Counterfeits Act) .
According to an open letter by Internet Engineers to the Senate, the COICA risks "fragmenting the global domain name system" because censorship/blacklisting will cause "alternative name-lookup infrastructures [to] come into widespread use."
This means, folks will start using non-ICAAN registries to find domains that are blacklisted by the US government. Inevitably this will lead to cybersquatting and other issues as people grab up the domains on alternative DNS systems.
Bad for the Internet. Bad for domainers.
