I am just thinking about showing some adult cels 
I got purely accidental ;-) . But what is the 
best way to do so?
For example AWS does it with a warning and the 
question for the age (http://www.anime-world-
star.com/18cel/atop.htm), another example is Ta-
kun's Cel-Site, where you need a password to look 
for adult cels 
(http://cels.de/CelHP/maineoscels.htm)

Thank's for any suggestions! ^^
