i can imagine how this can potentially turn out bad for uploaders - as it is rather difficult to imagine that someone would upload a copyrighted material 'incidentally', but for downloaders? - if you just download some file that has a name / extension which says nothing about its content, open it, and hey! - there is something copyright protected there! - you can always say (in theory, at least) that it was by a sheer 'accident' (pressed a wrong key or something) -

- whether such assertion would be trusted is another issue though
