@ -11,15 +11,15 @@ TOP 500.000 websites, I looked at the advertising industry itself, to block the
obvious benefit of low maintenance effort (for me) and low performance impact (for the adblocker you are using).
WHY USE A MINIMAL BLOCKLIST?
Number 250 on this list only has a marginal market share of 0.1% on the Alexa top 10000. That is why I use an adblock extension with an
easy point and click mechanisme to block or hide annoying stuff on the websites I have added to my bookmarks. No matter how large the
blocklist will be, your blocklist will always be missing trackers on websites with low visitors.
Number 250 on this list only has a marginal market share of 0.1 % on the Alexa top 100000. Imagine how effective URL number 50.000 will
be of your blocklist. Fair chance it will never be triggered. Some adblockers have an option to exclude URL's with low usage (like
AdGuard 'use optimized filters' option) or periodically filter out dead URL's (Opera's and Brave's build-in adblockers).
Problem with most community based blocklists is that they are not well maintained. Opera once checked the effectiveness of Easylist and
reported in a blog that 20 percent of the listed URL 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). Scientifics studies showed that large blocklist are (a little)
more effective on 'long tail' websites (not in Alexa top 500.000), but a little less effective on Alexa top top 500000 (websitws with
more than 2000+ visitors per day), because common blocklist trigger adblock walls and anti-adblock measures.

ALTERNATIVES
When you want a common use well maintained small blocklist, use most Disconnet common Ad-filter or Peter Low's blocklist (over 3000
