Same, I've only seen two ads since they started rolling them out. The first time, you could report them as spam, so I did so. The second time, months after that, I reported it as offensive. It might not make any difference, but I can say that compared to most people I know that use Instagram, I get almost no ads, the last one being three months ago.
