Re: First questions first
Just like you, I filter out all adverts, and as with everyone's exposure to them, the advert still gets brain space.
Purposefully ignoring an advert does not stop that advert from subliminally working on your neurons and advertisers have known this for years, hence the furore over ads that ran for only a couple of frames in films and tv. Not long enough to notice them, but your brain still saw them, leaving you wondering, why all of a sudden you craved chocolate.
Short of going all biblical on your offending eyes, I'm afraid only an intensive course of rational reasoning is going to stop you from being influenced by the devil's little helpers.
