Dim BG not working

#1
When the page is loading it works, but as soon as the ad(s) finish loading it resets to 0% dim and changing it at that point does nothing. Before today I didn't even get ads because of ublock origin, but now they get past it somehow and half of them are shit like "only fine girls on this website" "not like other dating websites". Does anyone know a ublock origin filter that can remove them?
