I also have some gripes about BP's moderation policies.
In my opinion, too often BP allows comments to descend into name-calling and ad-hominem attacks on those who post sentiments not in line with mainstream opinion. Some of the comments are distasteful and not on-topic. This isn't proper and BP needs to be stricter in controlling this. Besides, being civil lends weight to one's words.
BP also publishes letters in Postbag that contain widely-debunked conspiracy theory nonsense, anti-vax cant and fact-free assertions about Covid and other issues. Since these seem to be genuinely-held opinions of those who post, especially if real names are used, I'm not sure what BP should do about it. But some posters submit this kind of stuff on an almost daily basis and that's perhaps a bit too much.
Then there are posters whose opinions may be genuinely held, but are expressed with such consistency and frequency on certain subjects that many readers might come to the conclusion that they are operatives similar to China's wumao. I realize the difficulty in differentiating between genuine reader opinion and that of possible volunteer or even paid operatives and I have no idea if any of BP's posters are working at the direction of others. But some do seem exhibit such characteristics. At least Russia's ambassador, when making outrageous statements about his country's war against Ukraine, is identifiable as a government mouthpiece. It would be nice if such disclosure were forthcoming from others if they are also posting as part of a coordinated effort.
