Since a month many site place their adspam with random classes so you can block it but the pages reloads and renames the class and shows the spam again.
This cannot be solved blocking scripts on the sites or tell adblock what NOT to allow. Its endless.........it needs to be reversed.
It can only be solved in the way to tell adblock what it should allow - blocking all other classes.
Like on onvista.de ONLY container1 should be allowed and nothing else
