Maybe the answer is that every submission is randomly peer reviewed by other randomly picked editors, rather than moderated, its at least checked in a way that you cant easily compromise.
Perhaps, but if the ideal is to have peer review, then it implies peers and that implies a level of expertise. How do you ensure the “random” editors reviewing something have the necessary expertise in, using the given example, 10th Century Moorish art, to know if what they're reading is correct, or merely highly plausible cobblers?
That method may remove any “compromise” from having egotistical moderators, but it won't necessarily ensure quality is maintained.
I suspect, ultimately, that if you want material of a quality you can be sure you can rely on, you have to go to a source that rigorously (and therefore probably expensively) vets it's contributions. Encyclopaedia Britannica, maybe, or a relevant and specialist magazine. Wikipedia, as I understand it, relies on the garbage being picked up by enough other people to flag issues, and if you use it (and I do for some things, but emphatically not for others) you just have to accept limited certainty as to voracity. If that isn't acceptable …. go elsewhere.
Wikipedia is what it is, which is a good idea. What it is not, however, is a faultless Oracle of Delphi. We just have to accept the limitations, which are both it's biggest strength and at the same time, it's biggest weakness.
