A scammer tag wouldn't hurt them, you have to go after their cash and for this you would need to involve a legal entity. I'm really curious if their business practice are conform with US law. Selling products under wrong promises (ROI prediction), sending out products as samples even they aren't. Import products without needed certifications, let customers abroad pay in foreign currency to private bank accounts (chinese customers could pay in RMB to an chinese account). Using customer products for own profit before delivery,.... Is all that really legal in US? The list could be even more extended, could be worth to let an attorney look into this case, all this points looking suspicious to me.
I agree a scammer tag won't do much.
I guarantee if they keep delaying and not delivering more batch 1/2/3 machines and chip orders, there will definitely be some people filing lawsuits against them (me included if they keep delaying or just ignore me and never ship my equipment.) There are several lawsuits forming for BFL customers that I've heard of, Avalon's day is coming too if they don't get their stuff straightened out. I believe Avalon is a USA registered company by Bitsyncom, so it is certainly under the jurisdiction of US courts.
CoinHoarder is correct. Avalon can be sued for evidence of economic loss and false advertisement. A class action lawsuit can be put in place as well. On a criminal standpoint, Avalon can be prosecuted for money laundering in the U.S.
I've been extremely patient. I am consulting legal action now with my counsel.
