Why not just make a seperate section for first/second/third time submissions? Have the site notice if you've posted before, and redirect you upon clicking apply. Then select some people who have no problem reviewing those 5-minute hacks, such as myself, and have them operate on those submissions.
Granted, people could take advantage of this by posting four times, but you can avoid such tomfoolery. Simply make it so the people who moderate the bad hacks, can decide if a fourth post may be a bad one. For example, say FreddyKrueger submitted his hack for his third, time. If, since his first submission, he has neglected to follow any guidelines, the moderator(s) whom are reviewing such a hack, decide whether or not the hack is worth the Hack Moderators' time. If not, (s)he will continue to be redirected to such a submission form until improvement is shown. Hack Moderators also may have the power to push hackers down to the submission form [to which I am referring to], as they see fit.
