So first off, I vote that people who are not logged in should not be able to read all content on the site. Rather, I understand that having crawlable content is a way that forums get new users, and so many there's a scenario where 90% of the content is crawlable. But when users want to discuss the current administration and sensitive topics related to that? It's going to have a chilling effect if we know big brother is watching. (Obviously big brother is always watching unless you're accessing this site through a heavily encrypted and anonymized VPN, but still.)
Secondly, I think it's surpassingly difficult to determine what amounts to a "guide to committing crimes" these days. So if I post gu|de to d0xxing, then that flavor certainly looks like ban-bait. But if I post: How to Do Real Estate Investment Research, with a lot of the same content, it passes muster? I mean, this is not a new problem. I'm just saying, if we talk politics, someone is gonna say we should do this or we should do that or the other thing and you end up in a gray area before you know it.
