I really didn´t liked the public voting method from the previous contests. Some awful entries got within the top ten because they surely voted their own drawing like there´s no tomorrow. One of the entries got banned in the finals for something alike to that, besides other reasons I didn´t fully understood.
If anything they should allow voting to registered users only and control in case there´s some multi accounting going on.
Which entries did you have in mind, out of curiosity?
As for that disqualification incident you mention... hah, you should have seen the damage control from Creepo once I pointed out what was being said over in a Spanish forum. I'm the guy who found out and posted about it. In addition to that he posted a journal, a poll, and an edited version of his picture to DA, essentially triple spamming his watchers' inboxes with notices to vote for him.
Something was incredibly suspicious as soon as he entered the Strike Man contest and won by a margin that was never, ever beaten. It was triple the win margin of anything else in any other public vote Capcom contest whose vote counts I know of. It was unbelievable. Inconceivable, even. Hence why I looked.
Some extra fun information I never posted anywhere... I can tell you that Creepo's DQed entry received around 540 or so votes, out of a maximum of 4,300 or so if my memory serves. I know this because I viewed the source code, which revealed these numbers. So, it is conceivable that even with the cheating he could not have won.
As for the actual winners...
The biggest surprise was third place. I can actually tell you that the final contest's third place did not do anything. I searched high and low for evidence. Completely legit. Tiny fanbase too. It was the only... action shot of the winning three, so I imagine that played a role.
Second place, Andrew Dickman, and I am going to speak plainly here, essentially won due to his massive DA fanbase. He posted a journal and an edited version of his contest picture to double-notify his watchers to vote.
First place, Hollow Zero, posted a journal entry explicitly in response to these DA entries of Creepo and Andrew Dickman, but their fanbase is a fraction of both's, like... a tenth. Searching turns up no foul play.
Ah, reminiscing...

As for the registered users restriction... That would help, sure.
Judging does stop outright cheating, but it comes at the expense of allowing mod/admin favoritism and wacky personal preferences to come into the equation, as this topic indicates.
