Make a wish is NOT a porn friendly charity.
They actually denied a check from one of our events after seeing a press release stating that we were donating 100% of the door to them.
They also support censorship and dictate what is considered a "moral last wish". Some of you may remember their fight with Ted Nugent a few years ago. A dying child asked to meet and go hunting with Ted Nugent as his last wish, Ted agreed and the organization denied the kid because "hunting is immoral". In response Ted opened his own charity and now has a hunting camp for terminally ill children.
What I have done historically is donate 10% of my profits each month to a different charity. I allow users to request their favorite charities and if their stats look good to me then I send a donation there. Id also look for a charity that has a low overhead. It amazes me how many of these groups actually have more than 50% overhead which means that half of your donation goes to administration...rediculous!
