You were banned for being caught entering PVE with illegal buffs in a screenshot in Before I doing something stupid. That screenshot shows that you asked only after doing what you wondered if it was allowed. Even entering the server with illegal buffs is already breaking S5#1 - Hacks (not exploits) as you had to use a third party program to apply the illegal buffs.
However that was not your only offence: you hacked on May 05 in survival, and were reported in Starlight godmoding in survival (who has proven to be really difficult to catch in the act) and also in one PM report. This resulted in your first ban in Ban. You have evaded the ban two weeks later on May 21 and were banned again in Ban.
In your first appeal you promised not to hack anymore but now you have done it again. Due to being banned a second time for the same rule, your appeal is denied.
