I ended up getting banned for even using x1 damage and dump enemies. But I'm happy, because I'm bored with the game and this is a good reason for me to give up. My account is close to 50k power, 3-15 hard mode and chapter 14 boss normal mode.
Congrats on your 3 weeks, but you didn't hide your ID. You should always hide your ID when showing screenshots of the game, actually for every modded game you play never show your ID.
If you are doing everything in the modded app, you need to uninstall the facebook app first. Then in-game search for the link account to facebook option.
