lol nice FUD.

Niggercoin is still in the waves blockchain but it wont show up on the exchange. If you want to trade that coin, you can still do it OTC. The blockchain is still trustless. They are coming up with a spam filter for airdrops since it only takes 1 waves to create a token.

Decentralized exchange does not mean its not moderated. Waves DEX is a combination of centralized gateways for clearance and blockchain for order matching. This way you get best of both worlds.
