Use Cyanogenmod and hosts file to block ads

I am running CM11 on a Samsung Galaxy S3. I noticed that add supported apps suck a lot of my data and are sometimes just producing plain buggy and annoying banners.
Block em!
ok So I googled it, a few decent hits are:

• http://www.howtogeek.com/140576/how-to-edit-the-hosts-file-on-android-and-block-web-sites/  Explains it well enough, create file in notepad - using ABD, copy the file. But does not give any usefull example blocker addresses to get you started.
• http://www.hongkiat.com/blog/blocking-ads-in-android/ Provides a way to do this using just your Android and Notepad on the PC , and some artfull copying + moving to avoid needing ABD. It also gives us 3 example hosts files to get started.

So let's try it out. But before we go, lets get our hosts list pre-compiled. I found more resources and a slightly old one here http://mathdotrandom.blogspot.co.uk/2010/12/block-ads-on-pc-android-with-uber-hosts.html

So far it's not blocking much, but it's a start.
