Instagram advertising was what finally drove me off the platform. An unstoppable tidal wave of poorly-targeted products including cheap sunglasses, bizarre "on-trend" t-shirts and other assorted crap by brands that sounded like they'd chosen their name from a random name generator. And the ads were just about every third image. Grim.
Sure, I understand what you're saying. It wasn't necessarily the poor targeting, simply the volume of ads that were pumped in and all such terrible quality.
