Thank you both for contacting them about it. 

It seems like this is something that they frown upon but may be unwilling to act upon. 

From what I know spoofing has been going on combined with using payment walls and vpns for those who are ineligible for Amazon Prime events and other issues that haven't been global. There has been no evidence that they are issuing suspensions or bans regarding these things. There is no evidence either that the amount of people who created secondary accounts for Morgl were ever given warnings, bans or suspensions.

However, it seems evident that there has been a large amount of gps and tavern fraud in this event so I'm thinking they may issue a statement (probably not since blizzard has always failed in communications to it's customer base) or change how things are in the future.

I do not think the negative press from mass banning players for cosmetic items with no bearing on gameplay would be a wise decision but it is a risk that people should consider. It would be easy to find those who have spoofed if they keep any records of gps location. 

My guess is if they see people who jumped a certain amount away from their previous location, got Nemsy and back may have Nemsy revoked and issued a warning at the worst. 

But from what others have reported from Blizzard they probably won't act on this. 

TL;DR Blizzard customer service has been quoted as saying spoofing is against policy but seems unlikely to act. Proceed at your own risk. Get her legitimately if able.
