Yeah, Facebook can not know when your adblocker is blocking those posts, unless they did it themselves.

Facebook has groups, and unfortunately, that’s a pretty important feature. The car groups I belong to are hardcore track drivers and DIYers that share knowledge (problems and resolutions, alignment specs, tire and wheel experiences, custom parts, parts swaps, etc) and independent manufacturers who make stuff that isn’t otherwise easily available.

Until there is a solid replacement for that, I can’t get rid of Facebook proper.

Last time i checked, facebook had intentionally scrambeld the html attributes like “class”. where other sites would use something descriptive like <div>...</div>

facebook would instead use <div>...</div>

or some random string for a post to make it harder for adblockers. However its also easy to trick adblockers with

<div>...</div>

where the class “ads” is defined as general rule in uBlock origin, and would hide the friends post.
