I’ve never had a problem with ads made in this way. My only complaint would be it looks like an actual post. Even though OP is just sharing it, a filterable tag, like we have for nsfw, would be nice.

This form of “passive marketing” (I’m making up terms), I.e a random picture in the feed that you can easily scroll past is fine (assuming its marked appropriately and there are not too many). If the post catches attention enough that people start sharing it because they liked it, the marketer has done a good job. I also consider banner ads “passive”. If they actually filter out the scams and malware, and if someone wants to sponsor Rod’s Radical Recipes with a banner ad, who cares.

I do take issue with I’ll call active marketing. This is an ad you’re forced to engage with, like an unmutable gas pumps that’s playing audio, a commercial break or a pre-roll add. If I’m getting something for free, then sure an add or two seems reasonable (well, 15 years ago it did), but I’m already paying for the gas, shut the fuck up and let me enjoy my 3 minutes of stress watching the numbers go up without some guy screaming about beef jerky.

Edit: reworded the second paragraph, definitely didn’t look at the background too quick and think it was a real poster somewhere and talk about random posters on a wall…nope defiantly not.
