Someone mentioned dirty advertising coming to new highs... I was wondering if any of the parties is actively engaged in Internet advertising - I don't mean straightforward ads like banners or email marketing, but more of the "sneaky" stuff, i.e. social media, search engines, etc.

I wouldn't be surprised, though probably it's something they wouldn't really want to talk about.
