This tip/ad discussion reminds me of the equally idiotic and misleading Facebook post types. Instead of the correctly labeling all ads as, well, ads, Facebook have some ads called "suggested for you", some are completely unlabeled with only a "follow" button to start following, some ads are labeled as "sponsored" etc. I think they are doing this to evade legal limitations they might have otherwise. Last time I used Facebook it showed me 25 ads in a row (I counted), without any of my hundreds of follows with active feeds. Truly insane company.
