It looks as if these are new ads that can't easily be blocked using our manual blocking assistant, and that the Czech-Slovak filter list doesn't know how to block on its own. Please report this to the Czech-Slovak filter list maintainers so that they can update their filters. You can find the contact info in our Knowledge Base.
Here are some tips:
Name your topic for the site where you're seeing the ads.
Note: If the site contains adult content, please include "NSFW" ("not safe for work") in the topic subject!
Be sure to include your browser and version and which version of AdBlock you have.
Provide a link to the page where you're seeing the ads.
