I was notified that @tateisu's Mastodon app "Subway Tooter" has received a warning from the Google Play Store citing user-generated content that "incites discrimination".
A Mastodon app does not host or promote any content. The user types the address to connect to. The responsibility of moderating resides with that server. So unless Google is going to drop Chrome, Firefox and Opera from its platform, this is completely out of line.
