Just in case you didn't noticed, I am/was hosting
Pocket website. So if my customer tell me that 
they don't want their URL posted on this forum, I 
guess you will understand that I won't let it be 
posted. Or is there a special reason why I should 
make my customer angry ?!?

I don't need to prevent "competition" by deleting 
their URLs for personal gain, as you put it : When 
I buy cels from Pocket, I don't do it on their 
site, but directly from them, usualy while 
drinking sake in a Tokyo's restaurant.
