First of all, my meta apologies for taking over the blog section with a post that's meant to encourage discussion on how to prevent this flood of 'passable' accusatory blogs in the first place.
What I've observed over the few months that I've been a member here is that most of the people who participate in contests are genuine enthusiasts who do it because they like CP; most of us aren't here to just inflate our ratings.
What if we we could put a system in place that is based on 'trusted members' (like trusted participants, but a bit more strict) volunteering to personally inspect a few randomly assigned anonymous submissions and check and flag submissions for things such as code obfuscation which are easily able to get through today's Plagiarism Detection System.
Because the entries would be anonymous and people would have no way of knowing which users' submissions they'll have to scrutinize next, the chances of concerted mob behavior to game the system would also be very, very low...
What to do with the submissions which have been flagged a certain number of times is bound to remain an open question for at least a while and it would be great if you could share your suggestions...
