... We do what I suggested. We tighten the grip on any low quality post, irrelevant if they have a signature or not. The only way to do this that I can see is create a solid ruleset on what is and isn't allowed in a post and enforce that ruleset strictly. This would be the only way to deincentivize low quality posting.
Would be a huge leap forward.
Odd that a community with so many coders, i.e. people who work with and understand closed formal systems, seems set against doing just that.
The fact that a post is "low quality" or "irrelevant" is very subjective, and human judgment needs to be made to make this determination.
And that's why IRL we don't have laws prohibiting "bad things" or "things that are wrong."
"We should!" you say, "Why don't we?"
Well, because rules that poorly defined (open to interpretation) are junk rules, making a ruleset containing them a junk ruleset.
Let's try to create a set of rules that are not junk.
