I get contacted by advertising agencies fairly regularly. Most of them are similar in their offering, and most of them perform equally badly. I suppose if they performed well they probably wouldn’t be contacting me as they’d already have publishers queueing up to display their ads.
The latest one to join the batch is IronSource which differs from the crowd by offering installer advertising based on InstallerCore. As customary for these types I declined since I’ve never seen an installer based advertising solution that wasn’t basically a scam and based on tricking users into installing the offers. IronSource was persistent, though, and told me how much money a competitor of mine was making, (thanks!) which was indeed a large amount of money.
Furthermore they assured me they were “one of Google’s biggest partners working directly with their compliance team which means we have to follow their strict guidelines.”
Figuring it couldn’t possibly hurt to check it out (this is called foreshadowing) I went to my competitor and downloaded the installer. What I experienced is best described in images, anonymized to protect the innocents who just want to make a lot of money.
