I suggest that Bitcointalk ban all Defi platforms as soon as possible, and wordfilter their domains, why wait for a verdict and risk the forum being identified as a place where such services are desirable?
DeFi was supposed to stand for "Decentralized Finance". If they can be shut down, they're not decentralized and don't deserve to use that name.
I agree, you are right.
However, the front end can be banned, and the developers can be punished, like tornado cash...
