A motion to quash is basically you or a lawyer fighting a subpoena in these examples to get personal information connected to an IP address so an ISP does not reveal a persons information. The Electronic Frontier Foundation have an excellent page set up for this. Check that out here. You can do so by yourself or through a lawyer depending on each individuals choices or circumstances. There are examples there or you can check some links below. If you do not request for your documents to be sealed they will appear on the web for free in some cases such at Recap the Law or Pacer (Public Access to Electronic Records) for a small fee of each page.
That is why in some cases people use lawyers to do it for them. Some people have used their real names and the documents they submitted to the court are accessible to all online the web. That is what copyright troll lawyers want, ie your personal information so that is not recommended. ISP’s like Comcast do not try to help people and tell their customers to deal with it or they will release the information while others like Timer Warner try to fight it. Below are some example documents sent to courts anonymously labeled as John Doe etc so their real names are not used. In other cases a lawyer is used. Points made in these motions are out of courts jurisdiction, improperly joined with others etc. See below. But if you do not use your real name they most likely get denied that is the big BS behind this.
