Does B actually exist? I&#x27;ve never used an ad blocker and I don&#x27;t experience this. It&#x27;s either an exaggeration or you&#x27;re visiting some shady sites :)<p>edit: B did exist in the days of windows 95 but I don&#x27;t see it as a problem now. The biggest issue is auto play video or audio which even browsers makers are taking on.
