Let me explain what I mean. Big Brother Africa employs a 'voting block' system to avoid unfairness towards countries with large populations, e.g Nigeria. This means that Big Brother simply takes each country as one vote towards whoever wins in that country. So however many times we vote for Prezzo in Kenya, it will only count as one vote from the whole of Kenya in the grand scheme of things.
Given that the contestants who are left are pretty much guaranteed to win in their home countries, Kenyans trying to vote for Prezzo as much as they can are indulging in a futile effort. Prezzo is 100% sure to win the Kenya vote. What will REALLY help Prezzo's chances of victory, is if Kenyans somehow convinced other countries to vote for the prezzident. Preferably countries who's representatives have already been ejected from the competition, like Tanzania, Sierra Leone and the like.
But how can Kenyans convince people across the border, you ask?
The answer is: social media. Especially Twitter.
If Kenyans were to start a number of trending topics on popular hashtags, such as #stargame , it is possible to alert people from all over Africa as to how serious the 'Prezzo agenda' is. Hopefully they will get aboard the 'Prezzo train' and help him amass the swing votes from other countries.
