So here are my thoughts from an outsiders point of view (I have no involvement, or even really knowledge of what had happened, hell before this all blew up I had no idea who prom was until multiple people/sources state he is a P&Der, which is pretty scummy if you ask me).
Everything that was posted is very concerning, but to me stops short of scamming. Rather, i'd like to use the word scummy instead since Dan associates with prom.
I will say this however, and one more person to add to the list of people XC should have never been involved with was Jasin from Fibonacci. This one I can talk to at length considering I was the one who tried one last attempt to smooth things over between Jasin and his investors. Instead of helping, he completely stopped posting here and Litecointalk, along with delete his website. So he walked away with a cool mil or two of money.
The XC team defended him pretty hard, at first as a dev and then as a contributor, and that along with all of this recent information makes XC seem very shady to me. Again just an outsiders perspective.
