I see it happened to more people. I also got banned this morning.
- hacked the game,
- abused anybody,
- broke the game rules,
- purchased any crystals from unknown sources,
- played on hacked device - always use my iPhone12
Im running around 30th-50th place in both squad and fleet arenas. It is true that I face people with twice as mine GP in GAC, but I usually I loose these matches, except for times when they fail to attack me.
