No GM is at fault, they follow guide lines and rules set by senior staff and SE, It would be nice if they ever updated you on a investigation.

I'm speaking to SE at the moment about a banned FFXI account and it took 6 weeks for them to get back to me & now they say it'll take another 5 weeks to unban and restore the account. 11 weeks feels way to long for a senior GM or team member to just unban and update account infomation
