With statements like ... "Regardless, the point is that, if the only reason you consider DMing is to rack up DM Quests, maybe you shouldn't be DMing." ... you seem to have an opinion about why DMs should participate in AL and it doesn't seem very favorable to DM Quests.
OK, let's unpack that:
1. I made that comment in response to another poster claiming that, because CCC adventures don't qualify for DM Quests, therefore DMs have no incentive to run them.
2. If you really don't care about providing your players with a good time, or prepping the adventure properly, or anything except collecting those sweet, sweet DM Quest rewards, then yes, I think you should reconsider your decision to be a DM. I also don't see why that's a controversial opinion.
We have begun doing player audits before play at some events. Just a look through logs and seeing if anything pops out, like a 20 stat at 5th level or a magic item that seems out of place. As a DM I've asked a few questions, clarified what needs to be logged and asked some players who were bringing in non-AL characters to start a new one or grab a pre-gen. Nearly all players seem to be in accord with only new and young players being the ones who need clarification.
I'll actually agree with you on that -- most players are able to follow the basic character creation rules in the PH and the ALPG, and the few times I've seen errors, those players are generally easy to convince to fix those errors. Part of the reason why, though, is that the character creation rules are fairly easy to explain and largely unambiguous.
There are parts of the DM Quest process that are similarly well-explained and unambiguous -- the 'bonus for downloading the DM Quest pack' award is just fine, as an example. There are other parts that aren't as well-explained and are subject to significant interpretation -- I may think someone is cheating, but the player doesn't, and the DM at the table takes his interpretation over mine. DM awards that stack other awards, awards that are ambiguous about when they are awarded, awards that allow an open-ended selection based on criteria that can't be easily verified ("Of course I ran that mod! It was in a home game with my cousin and his friends."). Eliminating those types of awards, or at least modifying them so that they are less ambiguous and less open-ended ("You may select any uncommon item from Magic Item Table C in the Dungeon Master's Guide.") would go a long way toward making these awards less abusable and more easily verifiable for those DMs who prefer to do so.
