Yeah, hardly the worst case. I changed it to a temp ban.
I wonder when will your ban be lifted as it doesn't show up on your profile page yet, unlike other users that get the same ban status. Maybe it isn't taking effect yet on the account. Good for you that it's been changed to a temp ban, perhaps this serves as an eye-opener to everyone that you should not really copy-paste then post it directly here in the forum without citing the reference of it.
Is there any ban status in anyone profile? At least I'm not concerned about that. If someone gets signature ban, in that case, a message is displayed. He got a temporary ban, may be 1 week/15 days, not signature ban.
