This is exactly the kind of corruption which goes on in my country (Hungary). I hereby want to ask every HNer if he wants to team up with me and create a nonprofit startup which lets people document corruption in their country/city etc, things which are too small for wikileaks, or publicity like this.
I don't know about Hungary but in 3rd world countries (I am Brazilian) the worst is not that these things happen, it is that voters are too stupid to care.
One example: a couple years ago it was discovered that the president of the Brazilian Senate and Congress had a child with a mistress and a lobbyist office was paying the child support. It was a scandal that made big news. He resigned from the presidency but remained in the Senate. Later on he was reelected as senator and chosen president of senate again, last month. See http://en.wikipedia.org/wiki/Renan_Calheiros
Well, that's pretty much Berlusconi's entire political career: 20 years of scandals and still going strong. At the same time, you can expect at least one scandal per French president, but we seem to change them with more regularity.
Being in the minority doesn't mean they can be treated as outliers. Those ministers have multiple cases against them.
Given the nature of public attitude and their trust in the justice system in a developing country such as India, you can rest assured that the number of reported cases are below the number of actual occurrences.
I have been thinking about this for some time now and I feel the biggest factor in using this is localization. Nature of corruption is different in most countries, the startup will need to address that.
