My situation is very similar to you Guy, but at least you got an answer for your ban, even if it is totally unjustified. My 3 day ban is, according to Nexon is based on "freezing", sometimes they refer to crowns, other times to resources. They can give me a feed back about what I did wrong. I have never cheated nor wanted to cheat, I spent a small fortune of money on Dominations and now I got a ban with an ill fated accusation that I cheat. This defamation really bothers me giving me the creep, I do not like this defamation.
I do not know what"freezing" is, I do not even want to know it.
I'm scared to play after my ban is over, since I simply do not know what to expect.
I don't know what to avoid, unlike the Victory Chest case.
I'm buffled by Nexon's sanction against me, I feel like I'm left in the dark discombobulated and there is no knowledge I can access to prevent this kind of ban in the future.
