All I can think of proper evidence are the logs.
As mily and others, I'm friend with this girl and I saw how her brother advertised in the middle of pront.
Of the facts of that time and that I can barely remember is... Her bro was in ~~Legends~~ guild.
Mmm i dont know if it can be done but, if gms have access to her and his account, you could see the diference of tier they were, a.f.a.i.k. and could use that as proof the two of 'em are distinct people.
All in all, I thought perma ban is perma ban and cant be overturned, thats why I didnt try anything to bring her back, but if something is needed, I can fully support Deva to come back here.
Thanks Mily
