Hi Cheeky,
Following what Majin has said, you were banned for 24 hours for using the ballista and FFAing.
After first stopping you, you made another one and continued. I logged the ban as including 'bad behaviour' given the persistence and interruption of duels.
The 24 hour ban has since expired but I note this isn't isolated to KZG.
A 7 day ban may result if the behaviour continues.
Kind regards,
Duke
