Agree with what everyone has said, but what's not been mentioned is google searches, if someone now has your full name they can easily put it into google or searchelectoralroll.co.uk and find out the street you live in and the postcode along with anything else associated with your full name on Google.
I had a stalker client do this to me as my information was on 192.com and the one mentioned above and he gave the information out, so always Google yourself aswell, and if you are on any of those site put forward a removal request to get your information off there then go in Google and search "Remove outdated content" to get the link that no longer works removed off Google. I had so many things on mine, pictures, my office address and other stuff, but all has been removed and if anyone googled my name now there is only my Facebook and an old MySpace with no pictures that comes up! The rest are other people with the same name.
This was a life saver for me when said client was sending threats, it's actually pretty scary how many different places your name can be if you're on the electoral roll and if you have social media! I also agree never to use Facebook on your work phone or Whatsapp actually that's a bugger! X
