The Herald Sun today has content about crosswords, brain teasers. The editorial folk promoted it on the front page of the newspaper. The advertising folk, however, took money to cover up the editorial content, for an ad for an over 50s living business. They should carve out space for ads on the front page and not cover up editorial.
You cannot post an advertisement over an existing advertising without upsetting a 3rd party. But you can if the 3rd party is yourself. I would argue the editorial was placed specifically to facilitate the cover up.
I hate these stick ads.
