Uhhmm.... no. I'm splitting cost with him for witness server, and he pays the rest out of his own pocket. As director of a 501c3 charity myself, I am especially keen to where donated money goes. Cork is legit. In fact, YAH is more effective and efficient than any charity I have ever encountered. Do your research. Spreading falsehood generates bad, bad karma.
In fact, that photo of him that you used was taken the day he started his trip around the globe visiting all the charity projects that YAH is funding. During that trip he had a hospital stay from consuming local food/water. That didn't stop him. He continued the trip to visit every single point on the itinerary. You really did pick the wrong person to accuse. Very sad.
