The thing is is that AutoTrader is a website that advertises cars, they don't even have any other advertising on their site. And because EasyList doesn't like a word in their URL, the website breaks through no fault of their own. If the owner of the website is doing nothing wrong, the onus is on the owner of the blocking technology to come up with a system that works correctly.

I just visited the AutoTrader site (from the UK), and uBlock Origin blocked 34 requests related to ads and tracking. I recall in the past having been surprised at the number of extra requests being made via their site. They don't serve only vehicle listings.

Ooops, that's my misread of the forum posting from the AutoTrader team. They have 2 sites, one public, the other is a portal for car dealers to post cars in which they stated does not serve ads. The problem they were having though is that the ad blocker was affecting popup menus within their site.

In that light, I agree with your original comment, though it's amusingly ironic that their portal site was negatively impacted by mitigation measures against the kind of things their public site engages in.

It would be rather ironic if the post you replied to only thought they ran no ads because they forgot they ran an ad blocker.
