There's a nice and maintained host file here which blackholes most ad sites: https://someonewhocares.org/hosts/. As a bonus, it blackholes some shock sites as well.

The zero[1] version of it works a little faster.

I am using the Unified hosts file[2] (mentioned in the article), it is a great way to combine many other hosts including Dan Pollock's list.
