They already opened an investigation and found nothing on every account. Once again because she doesn't really have it.The problem with the evidence op posted is it's taken out of the game. A screenshot of viber conversation is not enough to get someone locked-up ASAP. If banning is based on viber, skype or fb convo then all players with personal issues against another player (I noticed that people here have a lot of issues against one another) will be banned by now. I could create one profile and call myself "Maha" or "Keiko", chat it to my personal account and viola I got an evidence against her. So ban hammer please, I need to get rid of her immediately LOL. But it does't work that way people. So that's the sad part even if it's legit. Although this is the case, I still believe that an SS of any kind is still enough to open an investigation but immediate banning? I guess not.
PS: There's nothing wrong if they are a farmer guild. At least they're not duping! HAHAHA!
PS: they are also duping and hacking =)
