I think something that's far too frequently overlooked is that the format itself is quite simple, and it's spelled out very clearly in the how-to section.
It should be kept in mind that people have taken it upon themselves (more or less thanklessly, I'd wager) to build a place where we can all come to share and check out set lists from shows all over the world, and it doesn't cost any of us a single cent. When the format isn't followed, the moderators have to fix it, and I'd imagine, certainly after all these years, that that's incredibly annoying. Frankly, I think not following the format is simply inconsiderate. It's been specifically suggested for a reason, and I think that should be respected.
