I do also think that this is a fairly long time tobe anned and if you ave learnt your lesson, your ban could be lifted provisionally.
No, it isn't. Do you know the definition of the word 'permanent' within "permanent ban"?
permanent
adjective
1. lasting or intended to last or remain unchanged indefinitely.
OK but:
indefinitely
adjective
1. unspecified period of time.
Please do not take that tone.
I said that it is a long time, "permanent" also denotes that!
However, as it is unspecified, it can always be changed.
