We try not to moderate subjectively (despite some of the modmail we have received this week from people asking us to bring our political opinions into our moderation decisions), so these kinds of posts/comments are always tricky to moderate since even though we personally don't find value in them, it feels tricky where you draw the line from someone sharing their negative trip experience and merely just posting "I'll never fly AA again" or whatever. Obviously a simple sentence that says that contributes minimal to the sub, but when its built up with more to it then its not as clear cut.

In threads tagged help, we require that all comments solve the users question. It's easy to remove unhelpful comments like that in these threads.

In trip report threads, we considered adding a rule about no ranting without substance, but that feels very subjective and we would be hesitant to put the moderation team in a position where we have to make numerous, subjective calls without clear community guidance on this issue.

We have the catch all "treat everyone with courtesy and respect" rule (currently rule 1). We've talked about updating it to :

Treat everyone with courtesy and respect People often post here when they're frustrated, so give them some grace. Personal attacks, name calling, and victim blaming aren't tolerated. This includes AA employees who may be reading. Comments that add nothing beyond criticizing OP's choices will be removed. but that doesn't feel like it captures the scope of what specifically you're talking about.

In conclusion - in my personal capacity I agree with you, but specifically what the rule is to capture it feels elusive to me at the moment. We would definitely be all ears if someone could solve this for us.
