Just want to put a warning out for people as I had never considered someone would do this.
Until recently I was in a guild that said they had plans for raiding and even had 2 raid nights out of countless cancelled nights. With that in mind I and other guildies built it up and created lots of mats and gear with raid night in mind and stuck them in the guild bank. We also, at the request of certain guild officers created trinkets and gems for them. Later, we found these items being advertised in trade for sale and on the AH. When confronted they denied it and then the next day the guild bank is completely emptied and 5 toons are transferred with all the goods we made. And the gold they made from selling our items. I am sure Blizz doesn't have a legal reason to pursue them, but I want to warn others of our mistake.
I take this as a learning experience and it is only WOW money I have lost. This is, I find out the 4th or 5th time they have done this. So if you are on Earthen Ring server now (That is where they transferred to) and see new people looking to join your guild or join their brand new one use extreme caution in how much you help them out or you too might find you are being used before their next server transfer. Almost like a WOW pyramid scheme.
And no, my current guild is not the one in question, I had only left token alts with the old guild as I had put a lot of time and effort into building that guild up.
