What ever happened to Bob Lucas Junior? He was one of the most vocal critics on IGG but I haven't seen a post from him for a while now; I hope he's OK....
Maybe he lost interest, or is it possible to ban people on Indiegogo from a project? I didn't find anything with a quick Google search. And looks like with Kickstarter, you can't remove comments yourself, but you have to ask an admin for it? If someone creates an Indiegogo project (it is easy with their lax rules, another free energy project would be fun
), I can add a comment with my Indiegogo account and we can test this, and the visibility rules of deleted comments.
