Harry,
It would be conservative of you to only credit IEBC and the Telcos for this. There is a very high possibility that the MP aspirant of today is refining the 'targeted campaigns' strategy. He/she has access to mobile money transfer transactions records at the shops; retail store transactions databases, of course Telco databases, etc - take all these multivariate data and subject it to some decent data analysis and voila - he/she can establish where you live or even how you are likely going to vote!
There has to be wider, well thought out and legislated means of protecting personal data. Not sure if any of the 'grand' manifestos launched in last 1 month touch on this sensitive issue at all.
