protecting copyrights with hashtags like Dropbox and going around it

this is how dropbox keeps copyrighted work from being shared - they think (it is all make believe)

But if you change the file (make it a second shorter for example) than the hashtag changes

at the other hand using names everybody knows or any system can understand is stupid as well

this is not to say that you should share copyrighted material

it is just to say that this system is only to stop the stupid and lazy uploaders

too lazy to cut a second from their file, change the hash and upload it

look out for more hashchanging tools coming your way (changing every file in your library, adding x bits to every file and changing the hash afterwards)

one is http://www.portablefreeware.com/?id=1535

this is all make-believe
