It's understandable for project teams to conduct witch detection, but what about the most basic transparency? Users who are deemed to be witch accounts should see clear reasons and evidence, isn't that reasonable?

Looking at it from another perspective, it's like buying something on an e-commerce platform, and the seller neither ships the product nor refunds, not even providing an explanation—who can accept that? Users participate with real costs, and at the very least, they should know where they crossed the line.

It's okay if they can't earn from fees, but such handling methods will only cause the ecosystem to lose trust. Transparent rules and clear feedback are beneficial for both the project and the users.
