When I checked EasyList for this filter, I found a lot of filters that are based solely on an element's dimensions. Is that a good idea?

Filters based on dimensions are present in almost every filter subscription, and block items that are of a size used exclusively by adverts.

Filters based on dimensions are present in almost every filter subscription, and block items that are of a size used exclusively by adverts.

Correction: "of a size commonly used by adverts." There is nothing that prevents any web site from displaying non-ads that just happen to be the size specified in one of the filters (like the site that I found). That is why I question the wisdom of using filters that specify nothing but the dimension of an element.

"Exclusively" is the correct term, as once dimension filters are found to have wider usage they are removed from the subscription. It is also important to note that there is also nothing to stop websites labelling items as adverts when they are actually the primary content of the website; far more false positives result from this action than from the presence of rules based on dimensions.

If it was "exclusively" there would have been no need for this topic in the first place, even the best generic rule would almost certainly cause a false positive somewhere (weather it be intentional or accidental).
