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.
Update: There is no sort of "tone" that I'm taking. If a ban is well deserved and one evades the ban, then a permanent one is what they deserve. Removing a permanent ban after a short amount of time (and I'm not saying that this is the case here) defeats the purpose of handing one out in the first place.
