I was almost an immortal rank in my previous account, once I update to v3.0.0 my rank downgraded to silver (I think someone said some posts before this was like a soft ban, like a punishment against mod users).
Unless someone here could tell us, if they have a legit account and, they also were downgraded, then I really agree they soft ban me.
also, I never associated my progress to google or facebook (no email associated ingame), maybe that was what saved me because after reinstall I started as a new player (with a new game ID and rank bottom - wood - again), not being affected be my previous account status. (Though this also depends how they do the bans. If its by IP or by account email or anything else I don't remember now. With this I should have been permanently banned but that didn't happened to me).
If you have an account associated, then, when ingame, access to settings -> your data -> delete your data and/or remove game association to your google or facebook account before try to start a new game after uninstall and install again.
other then this, then I can't explain why I am now able to play fresh the mod version without any issues.
