Updated Community Guidelines

The idea that we simply wrote things down quickly is not accurate.

What I got from Falconloft's post (and correct me if I'm wrong) is essentially this - unless you're doing something really stupid in private games (like most of the stuff mentioned in the rules, common sense things), you're left to your own devices there. If someone complains to a mod about "Explicit Material & Profanity" guideline in private games, than you simply show the mod that the themes of violence, sex, swearing, etc were specifically mentioned and established in the game ad/description and the complaining person knew what they were signing up for.

The spoilers rule seems redundant, honestly. If someone spoils something by accident - alert them of the screw up and inform them how hide those. If someone spoils things on purpose - then they're just be being an a-hole, and the ways of dealing with that are kicking them from your game (users), warning them to stop (mods) or in case of terminally braindead - mute/ban (mods). To me that's a natural extension of the "Etiquette" part and doesn't need to be mention specifically.

The tl;dr (as understood by me) is "we put some things in writing to cover our bases, but otherwise nothing's changing".

Also, I'll be first to admit that I don't remember what the previous policy looked like. I probably read it when I joined, but that's been a while ago. I imagine most of these things were there as well, we just never payed attention because that stuff doesn't come up often. A few clarifications might be nice to assuage people's worries about more mature content and gamelines, but other than that... If the mods say that there's not going to be any policing/witchhunts and such, than I'm satisfied. If a problem does come up, then hopefully these guidelines, common sense and just being nice human beings would be enough to solve it. Cross that bridge when we get to it, so to speak, instead of getting stuck in making super clear rules for any and every specific situation.

My other problems with the guidelines aside, I have questions about these:
Why is this the only guideline which lists the punishment?
What constitutes an "inauthentic" behaviour? If secondary account has a disclosure in profile, is that enough to count as being authentic?

Edit: just to clarify, I don't mind the wording here, I'm just trying to figure out if I need to go tweak some stuff on the second account.
And this is a very clear guideline which gets broken by recruitment posts, art threads and guides quite often. Maybe you should add a caveat to it? Something like "unless images are crucial to the topic or serve as non-intrusive decoration".

It seems I misunderstood the meaning of 'just simplifying things' then. I apologise.

Image limits: This is a holdover from earlier days, aimed at preventing spammy image posts that didn't really do anything else. The three image limit might not be practical now, as even one image of sufficient size can impact performance. We'll be looking more at this as well.

The guidelines will not be changing, just as they didn't really change from the previous version.

For instance, it is already explicitly stated in the guidelines that mods will not monitor language in a private game

Honestly, I'd prefer legal precision over generalized vagueness. But that's a personal opinion, so it's neither here nor there.

It just sucks that I'll have to self-censor even in solo games or risk the perpetual Damocles sword and the discomfort of knowing I'm breaking the rules. :(

{Side note: the guidelines also have absolutely nothing about private messages, which probably should be mentioned somewhere. As it is, the rules only explicitly include public forums and private games.)

I don't disagree! I added this to the list of suggestions when you posted it because it's a good call out. We'll be looking at it again.
