Got adsense account banned for invalid click activity, never done anything wrong in 3 months, also lost 3k gbp in adsense account. Made appeal, but it didn't helped, also got domain ban from adsense.
Then google play one time deleted app and banned my account for webview and affiliate spam, this means that I`m using not mine website in webview. After one month proving that this site is mine, I got back my account, with app that had 100k installs. After 3 weeks they deleted again app, saying that there is nudity, there whose only girl in bikini, after that app had pegi 18. So made appeal and get answer that they will not give back my app and I can try reupload same app with different package name.
Funniest when facebook full of porn is parent guided.
Another funny thing is that apps have rating like pegi 18, but screens must be appropriate for all people.
Next story, one years old app that have 1 300 000+ downloads, whose ranked very nice, but after google play algorithm update, lost all ranks, daily installs from 7-8k dropped to 700-500. After contacting google, they said app still ranks not bad, and I need to read aso book... So what is dam point working one years, investing hiudge money when you can lose all ranks in one night?
After that I read a lot of stories from other people, when google play staff is destroying people's lives with one dam click. Worst thing is when you work hard and fair, but other work not fair and google supports them. In google market it is tons of apps that have 30-50k positive reviews and that apps have less than million downloads. It is hard to get 5-6k reviews in one million, but this is fine by google.
