I am in doubt. I assumed that the use of a CPAN module is legal by definition.

I used WWW::YouTube::Download to ...uh ... download some learning videos. The script is just a modified copy from synopsis and pod, nothing interesting.

Now I get the error "Cannot find the link to video", whichever id I use. Since the ids are definitely existing I assume that I am being blocked.

So the question is - whether it is legal to use the module?
