You have been warned several times for spawnkilling and death evasion (Using /sync and /rc) by me and other admins, yet you continued doing these things.
How do I know you won't do these things again when you are unbanned?
Also, are you aware of the fact that ban evading will only extend the time of your ban?
As Fimpen said, small chances that you get unbanned, so think carefully about your reply.
