To clear things up, none of the bans that have happened are related to the 4.3.5 update release. Unfortunately, some of the bans went out on the same day, so there was a bit of confusion.
I made a post about how we have been improving our cheat and hack detection in Gems of War today.
Please be aware that after our new cheat detection has alerted us to the fact that a player is cheating, we then manually review their account to verify this information. If it is found to be true, the player is then removed from the game.
If a player feels that they have been wrongly banned they are welcome to contact our support, and we will investigate their account again.
It is also worth noting that even if a player doesn’t accrue a lot of trophies, or seem like the kind of person that would cheat, that they still may be doing so. Some players hack PVP, and these are easier for people to notice, but others hack in more subtle ways, or hack other game modes, which is less obvious to outside observers.
