It'd be better for non-English users to champion setting up channels where they can gather with other users who speak their languages.

It's a lot easier scale-wise to judge the quality of a channel than it is to go through hundreds of users and do the same thing. If channels are equipped with the right tool set then they can become self-managing. Ideally incentives/rewards should start to flow to channels, such that they can distribute them using their own mechanisms - again its easier to see if a channel is filled with bad actors based on how they distribute rewards than relying on an automated system for the same thing.

On a project I worked on recently I spent a couple of hours manually parsing reward payouts from a largely autonomous incentive system and found there were tons of users who had like 20-30 accounts attributed to them because they were all cashing out to the same addresses. An automated system can't really discern user quality, but channels (if managed by good people) can.

Creating language-specific channels for non-English users is a great idea to enhance user experience and community engagement. Empowering channels with the right tools and incentives can indeed help in self-management and quality control. Your experience highlights the importance of human oversight in detecting and preventing abuse more effectively than automated systems. Well-managed channels can play a crucial role in fostering a positive and trustworthy community environment.
