Don't want to get banned?
1. DO NOT USE DAMAGE MOD ON GUILD BOSSES, guild bosses have global ranking, and if you entered top list (top 200) while your level, gear, and other states are suspiciously lacking, you'll get the hammer.
2. DO NOT PUSH THROUGH STAGES TOO FAR, stage clear have global ranking, and if you entered top list (top 200) without actually looking possible to be there, ban is absolutely incoming. Currently safe stage to stay in is 70-50.
3. Don't chat. Even if you're not in top 200 rank of anything, if you show your stoopid arse on chat with low level and bad equipments while being in a suspiciously high stage, people will report you and you can say goodbye to your account.
4. Don't play the game. No play no ban.
