There's many things that stand out 1) Google Playstore allowing someone to impede on the TikTok brand. 2) The app getting 10k+ fake reviews. At this point can you trust the review system if it can be so easily manipulated? 3) "Strangely enough this is possible without getting any emails from Facebook." Facebook security is weak here. You shouldn't be able to change ownership without explicit 2fa verification. oauth tokens can be easily phished. password + 2fa device is much much harder. In general the trend I see is that Facebook and Google are driven to making ad purchasing as frictionless as possible. Having scammers, click-farms, fake reviews on their platform is good for them, it helps them make more money. They'll happily tradeoff human oversight/support and security for automated algorithms that optimize $$$ growth. Apple AppStore is polarizing. Some feel it has too much control, but on the other hand I find a lot less scammy apps in Apple AppStore than Google Playstore.
