I've seen many hat in hand threads, where the goal seems to be personal gain, so it's not a charity at all. To me, the most important thing is for us to make a clear separation between business propositions and charities. I spoke to someone who wanted to try crowdfunding as a means of buying a farm.
Around Christmas time we often see businesses beating their chest about some charitable offering where they give a percentage to the cause. Usually that percentage is so low, that it's really just there to
beef up their advertising. Some of the worst ones I've seen involved a breast cancer charity, where they
sell incredibly low quality tools with pink handles for about the same price as decent tools. Then 1% of the money goes to the charity. Almost any retail scheme is a very poor way to donate to charity.
It sounds like what you are talking about is an actual charity. So hopefully whoever does the vetting of these things, chooses the right category.
