I see the problem more in the fact, that a lot of publishers try to squeeze out some ad money from every single blank space still left on the page and fill it with third party services where they have no control over the actual booking. It is simply impossible to foresee what inappropriate ads might be shown if you don't now the pool.

In contrast to the directly sold banners, where the marketing team might just postpone a whole scheduled campaign for an airline when half the front page is filled with stories about a plane crash.

Still I think it's impossible to avoid some inappropriate ads at time and one has to live with it.
