@ -10,16 +10,9 @@ about the same advertising traffic on its own website.
Number 200 on this list only has a marginal market share of 0.1 % 1n the Alexa top 10000. Imagine how effective URL number 50.000 will
be of your blocklist. Fair chance it will never be triggered, because you never surf to the websites on which this tracker is used.
Some adblock extensions have an option to exclude URL's with low usage (like AdGuard or SmartAdblock) or periodically filter out dead
URL's (like Opera's and Brave's build-in adblockers claim to do).
Opera performed an analysis on the effectiveness of Easylist and reported in a blog that 20 percent of the listed URLs were dead and
another 60% had a 'hit rate' of less than 1% of all the traffic of the Opera browser users (having agreed to provide telemetry data).
Scientific studies also showed that large blocklist adblockers (AdBlockPlus and uBlock0rigin) were a little more effective for websites
not in Alexa top 500.000 (with more than 2000 unique visitors per day), but a little less effective on Alexa top top 300000 (websites
with more than 3000+ visitors per day), compared with small blocklist adblockers (Ghostery and Privacy Possum). Websites with many
visitors are more likely to install adblock walls to protect advertising income. Anti-adblock walls often check for popular content
filters, making it more likely to run into a adblock wall with for instance Easylist, see https://browserleaks.com/proxy
Another problem with community based blocklists, is that they contain a lot dead URL's. Low prevalence and low maintenance probably
is the reason that some adblock extensions have an option to exclude URL's with low usage (like AdGuard or SmartAdblock) or periodically
filter out dead URL's (like Opera's and Brave's build-in adblockers claim to do).
ALTERNATIVES
When you want a common use well maintained small blocklist, use Disconnect's Simple Ad-filter or Peter Low's blocklist (both have over
