I'm fascinated by the social cost of these spam accounts and apps. Who is installing these apps? What are the spammers getting out of them? Who is writing them? How much economic damage is being done by these apps, if you tried to sum it up?<p>To be honest, when I look at the mobile ecosystem, it seems to me that a pretty large fraction of the "legitimate" apps are barely better than spam. Most of the best freemium and gatcha games are pretty terrible, and I can only imagine how bad the bad stuff is.<p>Fortunately, there's a filter that can exclude free apps on Google Play. Seems to me, especially in the games department, it behooves you to turn that on. If you do, you generally won't be affected by psuedo spam or actual spam.
