Guys I think I finally figured out how to not get banned.
Step 1:
* If you are a new player, never do gods summons at all. If you want to do it, make sure your account is at least 6 months old. And even then, don't use it more than twice a day.
* If you are a new player, never have a army might of 5000!!! Don't, if you do have a army might of 5000 then don't use it in any match, if you go against these rule, you will get automatic ban within 30 minutes. Wait for at least 3 months before you start using cards with high might.
* Entering higher league doesn't get you banned, for anyone who said that it does, is not true at all, what gets you banned is your might that you use to enter that league.
* Having lots of diamonds doesn't get you banned either. Just make sure it doesn't pass the 4000 diamond mark in a day. And if you didn't pay real money in this game, then never allow your diamond to reach more than 50,000. If you do, the game will be suspicious and if they find anything crazy then anti cheat message will just trigger.
* Having many legendary souls doesn't get you banned, so you can have as much souls as possible but do not upgrade them until your account is up to 2-3 months old. The anti cheat checks your total army might and if it passes a certain amount, the anti cheat will pop up.
* If you are using game guardian to modify shop rewards, you are 50% safe, why? If you modify rewards that are too unrealistic to get, the game will validate your rewards, but if you make the rewards as realistic as possible then you will not get validated.
* If you are a new player, never do event shop bonus spins in a row. This will get you automatically banned. When doing the event spin, you can do it to the max and get the bonus spin, you will be fine but don't do it twice in a row. Do it every bonus spin in 6 hours. And don't do it more level 8 in the bonus spin or you get banned.
* Don't win too much matches in a day until you reach league 5. The game will find it very suspicious and if they detect any cheat then you are going to get banned.
* You can own different warlords but don't get them all in a day, you can get them one at a time, at least every 3 days.
* Never have more than 3,000,000 gold max except your account reaches 3 months old.
* Buying stuff with diamonds doesn't get you banned but don't do that 10× goddess summons. Avoid that at all cost.
* In wish shop, you are basically immune to ban but don't get too greedy because of the resources like diamonds, elixir and guide contribution points you will get. You can spin as much as you want but remember how much resources you are getting, if it becomes too much in such a short time then you will get banned. So do at least 16-20 spins every 6 hours a day and you will be safe. If you do all these then you will not get banned.
* Finally just to be extra safe, if you are done with the playing the game for a day, make you change your decks into weak cards so that might is low. If you follow all these roles then you will never get banned.
