Won't be the first time someone make a good looking website and whatnot just to scam. Never underestimate people when (possibly big) money is involved. I've seen it countless times before.

I don't need to contact the dev, he has all the info and concerns written right here, over 2 threads (he knows perfectly, anyway xD).

Only way I MAY remove the warning is if he changes the description, making it clear that it's not true there always will be enough btc to buy back std at GER (cause that's false xD) and that you can lose money there.

I said "MAY" because that won't cancel the fact he tried to mask the whole thing while holding all the money at his private exchange. Shady as hell even if he corrects the description. But I'll think about it.
He can use an escrow maybe: you send btc to the escrow address and he releases STD. Then I'll definetly remove all.

As for your rating, already answered: remove your one, which is an abuse, and I'll remove mine.
