The DMCA is ridicously unbalanced. There's no penalty to filing false reports and if you disagree with a claim you have to hand over your personal information and fight it out in court. This is hardly a surprise given that the DMCA was written mostly by the copyright lobby; sadly, the law is working exactly as intended in such cases.
It's time to redo the DMCA, but I fear the copyright industry has only gained a bigger foothold since the DMCA was written.
