The anti-retention vote would be more diffuse. People would have 11 contestants at first to dilute such a concentrated vote. Each week it would drop and get more problematic, but it would make it much more difficult to spoof the results. I think the ONE vote option is best but probably not economical or technically possible using phones. It could work on the internet... Except I doubt that even the internet could handle that much traffic flowing into one website... The bandwidth would be astronomic.
Oh, regarding the local Filipino newspaper. I wouldn't doubt that the same thing is happening in Filipino community centers and newspaper across the nation.
