In many ways we have a society where it is one rule for the rich and another for the ordinary person. A good recent example of this is Facebook, which is happy to let Donald Trump say things they class as hate speech on their platform, but won't let their ordinary users do so.

Edit: a quick search on the open register for Wolverhampton reveals Sahil's full address from the 2009 and 2011 electoral rolls. Which means you could have used 192.com [1] or whitepages.com [2] to find him and thus very unlikely he had opted out, as those sites use open (edited) register data.

DISCLAIMER: I work for one of the major credit bureaus but views are my own, and my understanding of the regulations around access to this kind of data is very shallow.
