I agree there is responsibility on both sides. Yes, lesson learned, always use escrow.
As rdanneskjoldr already touched upon, there is absolutely zero responsibility on our part to fix your screw ups that you made against our 6 month non-stop warnings of exactly this scenario. None.
Us deciding to help you out despite your fuckup is nothing other than altruism because we want as many good guys in IOTA as possible, but it's not something we are responsible for, you're an adult, you went against our advice and you got burnt for it, the fact that we are potentially able to help you out of the situation should not stop you from learning the lesson here.
When I say there is responsibility on both sides, I meant between the Buyer & Seller not the IOTA community. But the IOTA community should consider penalizing the scammer if it can. I believe that is what is being considered by the community at this time.
The idea to contribute some of the recouped funds to the IOTA Foundation is a sound one and hopefully will be considered.
