I disagree with your statistics. In fact, there may be more than 70% of bots in 2 million users, and 20% are farming accounts. Real users may be less than 10%.
For bots and agricultural accounts, I don’t think they are reasonable to get merit.
For users with broken English, posting a few high-quality posts in a local section is still very easy to get a merits，at least I think so. If you can't post at least 1 high-quality post in the local section, then you don't deserve to get a merit.
