They'll come right for us... mudcat.org... you know... if this is passed.

You have no idea how much pressure I get as it is now, publishers telling Google to block individual threads because they contain copyrighted material even though the lyrics we have are from 1906 and someone did a cover of a public domain song and copyrighted the arrangement yet...

The publishing company merely fills out a form online and the thread is blocked by Google.

I get an email (this one just 2 days ago, ON the 16th even, and AFTER I fought it once already in March) that says:

For legal reasons, we've excluded from our search results content located at or under the following URL/directory:

    http://www.mudcat.org/thread.cfm?threadid=26799

This content has been removed from all Google search results. Cause: Somone has filed a DMCA complaint against your site. More information. File a counter-complaint.

I need to file an actual legal counterclaim with proof that I have the right to "publish" that material that initiates a legal proceeding which essentially invites the publishing company's lawyers to start digging around the site. The last step of the Google process warns (in bold and red no less):

Be aware that there may be adverse legal consequences in your country... [essentially if I am wrong about the copyright infringement they still have not explained to me].

After we receive your counter-notification, we will forward it to the party who submitted the original claim of copyright infringement.
Please note that when we forward the counter-notification, it includes your personal information. By submitting a counter-notification, you consent to having your information revealed in this way.

My personal info goes right to the person who complained but I still don't know who they are.

This happens about 30 times per year, 4 times I've been in court. I mess with them sometimes just because I have nothing to lose, when they find out that I'm poor and host myself (no cloud or ISP to pressure) they usually quit fighting me. I'm a nut with an excellent philosophy education and way too much free-time. It's expensive to get into litigation with me. I make sure of it.

And SOPA was introduced by democrats, by the way.
