Saying "it needs to be done" is different from it CAN be done. Can the process be improved? Sure, most things can be improved. Will it be come perfect? Of course not, nothing in life ever does. The process can't be automated. Fallible human beings have to do it. As you say, some jokers may try to post the most obscure things they can to test the system and then crow when it fails. They have to strike a balance between exercising due diligence in ferreting out violations and spending an inordinate amount of time making exhaustive searches that will slow down the flow of items made available. To a great extent, they have to rely on the honesty of the folks making submissions, just as they do with every other term of the TOS, that and observant people pointing out the ones they miss. For the latter, I think a simple private message would be the most expeditious method. Public exposes are OK I suppose if they make one feel better. To the extent that they lead to improvements in the system, they can be even be a good thing but eventually, I think they tend to foster a climate of conspiracy theorizing where no conspiracy exists. One gets pulled and the other doesn't because people with the best efforts and the best of intentions screw up on occasion. Homeland Security nominees turn out to be duds, suicide bombers infiltrate mess tents, it happens to everyone and will continue to happen. That's just they way things are.
