Re:How can they catch them? (Score 1)

That is a good point that all they have to do is log on to your computer but that's only a preliminary sweep. They can't use what they find on your computer other than to identify you has a major file sharer. Once they file the lawsuit, they would have to subpoena your computer to prove anything (but this is only in the US, don't know other countries laws). They couldn't use a print screen picture because that can be easily forged so confiscating your computer is the only way to get both a criminal or civil conviction. I would recommend to people who feel that they might be targeted to keep their entire stash just 1 or 2 clicks way from deletion using a deletion program that doesn't just remove the file from the FAT but completely rewrites over the file.
