matchboxbananasynergy Lists have to be added carefully in order to not break functionality people expect, as that in turn means they have to disable adblocking, given the approach of using a unified set of lists for all Vanadium users.
Great to see content blocking coming to Vanadium <3
However, the current filter set leaves a lot to be desired. A lot of ads and trackers don't get blocked. One important example is YouTube, which you can't work around by using a blocking DNS.
Would highly recommend to use uBlock Origin's default list set. It has very good blocking results and I almost never saw any breakage over the years of using it. Alternatively Brave's aggressive blocking mode filter set is also worth considering.
Since you strive for a homogeneous crowd of users, better blocking is important, even if it means risking breaking one or two websites a user visits a year. It's still better than users making workarounds by using individualized DNS blocking, which is also fingerprintable and can destroy their anonymity.
