How about muddle authors?
Check http://download.cnet.com/VirtualDub/3000-2194_4-11569667.html
This upload to CNET was maked by Avery Lee, who is author of VirtualDub.
(But I don't know how about authentic of this info).
You can found link to http://www.virtualdub.org/ by clicking text
"See full specifications" or by clicking text "From Avery Lee:".
And next you can found sources.
I know that author can do anything with his work, but site page say:
VirtualDub is a video capture and processing utility licensed under
the GNU General Public License (GPL).
but such statement is false:
provide clear instructions people can follow to obtain the source
Another problem that I see is harm nature of current business
model of some sites which make dumb cloning. Compare:
http://avery-lee.software.informer.com/
http://fileroad.com/details/avery-lee-virtualdub/249
http://www.sixfiles.com/dbase/files/avery-lee-virtualdub.html
If original source publish software correctly cloning bots
can violate GPL.
