I am not sure whether there's anything you can do, but:

chip.de has videos that play automatically when loading a site, which is extremely annoying. After a few seconds of loading the normal videos, an ad video starts playing.

You can find an example here:

Is there anything that can be done about this, or is this a matter of up-to-date filter lists?
