I'd say it depends on your legislation and on the question if you are talking about the program itself or about the process of using it to download material for which you do not have any rights.
I guess in austria, for example, it should be legal, because it's not explicitly forbidden to download copyrighted material, just to share it with others.
But: I am no laywer :)
Most likely not. Until evidence is presented that proves otherwise it would be smart to assume it isn't private either. Doing it yourself with a Seed Box is the secure(r) way. I echo the "cool" sentiment though.
Using seedboxes is also part of being a good torrent neighbor -- most private trackers have upload ratio requirements. These requirements are infinitely easier to meet when using a seedbox.
Based on the title listing, no. At least some of these are licensed in the US, moving it out of even the grey area that might exist otherwise.
We don't host any of the content its aggregated from public ally available websites the application is simply a search engine with links to where the content was found.
Users who upload videos to these websites agree to have the rights to do so.
Then you making your thing could be okay, but someone using it is still probably not. :)
