That’s true, but incomplete. According to their own words, they don’t log into the server to investigate, but they do get the copy of the database and “visit” that copy.
I agree that’s not enough for certain kinds of infractions – like hacking, for example – but it’s quite enough for building-related rules.
The problem with those particular rules isn’t the due diligence, it’s that no one is sure what they mean anymore, given a number of cases we’ve seen where not even the staunchest supporters of the rules could find anything concrete in the rules and had to resort to arguments that boil down to “well it goes against my personal preferences”. 
You missed another one:
The gist is that if you’ve built something big that has no other purpose than to look good and show off your building skills, then Funcom could decide you’re using the land claim in a way that needlessly takes up space other players could come and claim.
Is that a good rule to have? That’s debatable. Is Funcom doing a good job of enforcing it transparently and consistently? Hell no.
I do. I’ve played on many different official servers, and I haven’t seen a single one without some asshat building some huge theme park that makes the whole server worse, either by screwіng up the performance or by blocking important stuff.
I’m not saying that was you and your buddies. I’m saying that some people get tired of that shіt and adopt an extreme attitude.
Why brimstone? You can also get brimstone in many other places and ways, can’t you? Oh, that’s right, because brimstone is important to you. 
See that, @Brainalyzer? This is why some people get “arrogant” about these things, because there are always those who want to make excuses according to their own whims.
There’s literally no “help” to be had. The enforcement of the rules is inconsistent and opaque, and we’ve been yelling at Funcom for years that they’re doing a shіt job and they’re improving.
The ToC was supposed to help players. Instead, it’s a risk everyone has to accept and learn to deal with. Anyone who doesn’t is gonna end up having a bad time.
The easiest would be to put it on ignore and let it play itself out. Sooner or later, it’ll get closed, either due to inactivity or due to people being shіtty to each other and mods stepping in to close it.
Ironically, most of us who kept pestering them to put up some rules were not asking for any of this shіt. What I personally wanted out of it was the ability to deal with trolls and griefers who liked to wall in other players’ bases, wall off new players’ spawn points, and block entrances to dungeons and important spots.
Instead, they came up with a bunch of rules they failed to enforce consistently or in a timely manner, then made the dumpster fire even worse by changing their minds about whether you’re allowed to block things like world bosses.
