Better to stick to a few blocklists which are actively maintained (e.g. Peter Low, Adguard, Disconnect), meaning old obsolete entries are removed (problem with community lists is that many people add new entries, but few remove obsolete rules).
Example uB0 with
- easy list + privacy = over 45K rules, go to a few websites, e.g. forbes it shows 15 (out of 23) domains connected
- Peter Low's + Adguard privacy = less than 7.5K rules, same forbes website shows 16 (out of 27) domains connected (on firefox in stead of Peter Low's list you can also use Disconnect Malvertising filter which includes Peter Low's list, but adds 2.5K rules for latest malvertising links).
You will see simular results on popular (Alexa top 1000) websites.
When you visit that website with Chrome and the Avari Safe Browsing extension installed, you will see that it blocked 12 ad and tracker networks (which is pretty close to uB0 score with < 7.5K rules). Advantage of Avira Safe Browsing it does a better job than a uB0 with many filter lists enabled (see Evjl's rain
video) and triggers less adblock-wall's.
