And yet, here you are, validating the very criticism of your heavy handed authoritarian nature. You make the very same kind of authoritarian claims of "evidence" (where is it, show it and provided it for public scrutiny and audit then) and you weigh that "evidence" against arbitrary (yet comically inline with your own self-interest) measure against ambiguous rules. It's the authoritarians' playbook 101, regardless of whether the authoritarians are competent enough to recognize it, let alone self-are enough. (pro tip: you guys never are … never)
Just try to reflect on the authoritarian and supremacist mentality you have with language like "It isn't a good use of resources to patiently coax them to improve or even to reply to their posts at all"; yet your expend resources to censor and control and rule with an iron fist anything that is not to our liking.
No one is talking about obvious spam or any kind of illegal language like credible threats of violence or stalking or bulling, but if you were at least honest with yourself you would acknowledge that it has nothing at all to do with "good use of resource" and all to do with control. Because it is irrefutably true that if it were about "good use of resources" you would wholeheartedly avoid censorship of legal language and not violate what what has been deemed a human right, free speech.
You types, people with the authoritarian supremacist mentality you clearly have, are always quite to rationalize why it is fine that you be the arbiter of right and wrongthink, but it never avails you of the inherent evil exhibited by controlling speech and expression, no matter how much beneath you or inferior and unworthy you decree that speech to be.
