You'd have to say its true..
but actually, the main problem is:
artists submit their work to low-security websites. (Power-fusion is really secure, Newgrounds is pretty secure and Flashplayer is half-secure)
random people simply come and take it, submit it to different sites.
so if you were to blame ebaum only, you havent looked at GPrime, albino blacksheep, etc.
and if you press "remove flash" on the site, it will send an e-mail to ebaum, not PHP programming, and you might want to make him verify somehow that you are the artist. So since its' e-mail, it takes a long time to remove it.
Solution: make the .swf file put in a new window, and so that you can't right-click the background, f11 closes the window (in flash) and make the window non-resizable.
however, i would say ebaum is responsible for not checking copyrights.
