Strange I don't see a No option on that poll... hmmmm
serious answer:
Nudging teammates into enemies is teamkilling and grieving, this being your 6th ban 96 hours is anything but harsh in my opinion. Your friend recieved a slightly harsher ban of 48 hours as his second ban only because his last ban was for the SAME thing. If you want me to go by the same ratio as I did your friend I can I guess but I figure you like the 96 hours rather than the 144 hours.
The ban timer will expire on its own.
