Do these ads really seem like they would perform worse than typical banner ads? You're right that accidental clicks may happen more often, but you don't pay per click. You said that "nobody wants them, everybody ignores them", which can be said about any kind of display advertising if you don't like advertising. At the end of the day, an ad campaign can be a smash hit with click-through as low as 1%, or even lower depending on what you're selling.
