Can’t allow? Can’t allow?
First of all, unless you yourself are a moderator or one of the bloggers, I don’t think that you are any authority on what can, or cannot, be allowed here (nor am I, in case that isn’t clear). You have an opinion on how the site should be moderated, which is great, but if I were a mod, and someone started telling me what can or cannot be allowed, I would probably banhammer them (for a nominal period), with the note, “Google the difference between ‘can’ and ‘should’.”
It’s probably a good thing that I’m not a mod.
Second, @codinghorror’s mantra, for as long as I can remember, has “flag anything remotely objectionable, and let the mods sort it out.” The quote from my topic post, way, way, above, was “There is a general lack of flagging.” How do you not allow someone to flag something that they find objectionable without disincentivizing flagging further (the exact opposite of what we’re trying to accomplish here)?
I can understand taking issue with the moderation (and I see about six different items on the master list of “Reasons Boingers don’t flag” that could be grouped under “disagree with current moderation practices,” so you’re not alone there), but the issue is not that someone was allowed to flag you.
Unless you can come up with a way to disallow flagging under the circumstances you describe that wouldn’t result in a further reduction in flagging.
Third,
Just agriculture? Agriculture is somebody’s trigger subject? Colour me skeptical.
And, finally, as has been posted previously in this topic,
9.Enforcement may be lax or draconian as befits the whims of the Entity. The rude will be eaten first.
Replying to someone, a member who has asked not to be replied to, may not break any of the Rules, but it’s certainly rude. And, perhaps the member you were conversing with was being rude, as well. With all that rudeness flying around, I don’t know why there’s any surprise that the conversation got eaten.
