What you referenced is not caselaw, meaning there 
is no legal precedence. And even though in your 
situation you were fortunate to have the site 
removed since you were the creator of the images 
and text, I still seriously doubt companies that 
own the licensing rights to DragonBall will 
actually hunt down this individual. Do you really 
think it's worth their time to incur legal 
expenses to enforce this? And say they do attempt 
to prosecute this, do you think the creator of 
the website has the monetary means to pay the 
company? Be realistic, companies do not care 
about petty websites like this one b/c it’s not 
worth their time. 

Lastly, the bottomline is, if you put it on the 
net, you DO risk people copying your work, either 
take 
abundant precautions or abstain from posting on 
the web entirely.
