There should be tough legislation to deal with these kind of "competitions". Here are a few ideas:
1) Each company running such a competition must make public the number of smses that were sent each week, total revenue, total payments and to whom! This should be given the same prominence as the advertisement for the competition itself. As a matter of fact they should be advertised together - same font size and all.
2) An
empowered and independent betting control agency should vet the whole process.
3) KACC should be required to randomly investigate some of the winners and their relationship with company running the competition. This should be mandatory even if there are no complains from any quarter.
These are money minting con jobs. I am reliably informed that the "Range Rover competition" dudes made 1.3 Billion [with a "B". LOL] profit! And get this. They didn't even have the prices when they started. They used the sms money to pay for the prices including the Range and kept the remaining 1.3B - Thank you very much!
Don't be shocked. Here is a possible scenario. 3 million stupid Kenyans each sends 10 smses [60/= each]. How much do you get? 3,000,000 * 60 * 10 = 1.8 Billion!!! 500m you pay for the prices and marketing and you are left with 1.3 Billion. Now imagine that some Kenyans sent up to 100 smses. You don't even need to reach the threshold of 3 million stupid Kenyans! Now imagine where even the winners are rigged! Do I need to go on?
Never count on making a good sale. Have the purchase price be so attractive that even a mediocre sale gives good returns.
