There is no such thing as a "safe mod." if you use any one of these apks, you are at risk of being banned. Sure, bandai doesn't take the time to comb through every player to find the modders and only bans the really obvious ones but they do from ocation find people who are not that obvious and ban them. Odds are you got unlucky or you were really high in the ranking for the tm because they do check the top like 1000 players to see if they mod and ban them. Don't stick out like a sore thumb when you use mods and you should be fine. Also, i got "temp" banned on a previous account back in april and still haven't been un-banned so i would look into getting a new account if i were you, which i was, and i did.
