I think retargeting ads can tell that &quot;you&#x27;re you&quot; and are capable of having implemented such check as a condition for not showing. But I don&#x27;t know for sure, I only had to deal with them once at my work, when the boss asked me to put some magic hash number in some frontend code.<p>&gt; <i>soon, on a website near you</i><p>Yeah, screw you advertisers. I honestly tried to browse with ads, but I couldn&#x27;t any longer and finally reinstalled AdBlock a few months ago.
