rkshooter proposed one possible solution
Create a new site. It needs to be very small. Set a link in the lagoon that points to that site. It is at that site where donations are made and then sent to Shark. The site needs to offer something to get around the rules of redirecting funds so why not set it up to provide wallpapers of sexy 3D calander girls but nothing showing genitals or nipples but still sexy. The donation could unlock access to them. It might be a way to get arround the rules.
What about the possibility of going completely the other direction!?
I have not the foggiest idea of what would be involved, but how about declaring yourself to be a non-profit organization? It might complicate things if you decide to change that condition later on, but it seems to me that Pay-Pal would have a tougher time denying service to any group carrying such a designation.
When it comes to binary, there are 10 kinds of people - those who get and those who don't!
