(yes, my PERSOANAL RIGHT to bear a firearm)
Freudian typo !
I have also had some of my AMVs removed or restricted by YouTube.
Although AMVs probably constitute fair use, it's a moot point in the case of YouTube because they (not you) are making money from hosting your clip, so they (not you) are legally vulnerable if the original copyright holder comes knocking. This is why their TOS stipulates that YOU must own the copyright to all the material you post.
Fortunately most anime publishers recognise AMVs as free advertising, and leave it alone.
The hardest part of climbing the ladder of success is getting through the crowd at the bottom.
