Positive stories about Facebook are rare these days, so it’s news that we have one: Facebook has expanded its Marketing Partner certification program to include Brand Safety products, which help advertisers avoid placements on sites they want to avoid. The first two partners are DoubleVerify, which verifies traffic quality, and OpenSlate, which rates site content.

Smartphones also raise privacy issues, especially regarding location data. This study from location tech vendor Blis takes a good look at consumer attitudes. Like other studies, it finds about one-third of consumers don’t want to share their data at all and the rest are mostly will trade it for discounts or similar benefits, often at a very low price. For example: 70% would let Amazon see their shopping history on competitive sites in return for a discounted shopping cart.

Remember the good old days, when lying was considered unacceptable? The folks at Iron Tribe Fitness, a South Carolina gym, are holding Meta to that forgotten standard in a class action suit alleging that Facebook overcharged advertisers as much as $4 billion by using one type of auction bidding process while claiming to use another.  Meta blames the error on a “software glitch” that began in 2013 and continued for at least four years.
