For the record, they never said using alts to gain more guild currency was ok. They said hopping to another guild to participate in a raid was. They also said anyone found abusing the feature would be banned.

It has come to my attention that there may be some unintended behaviour with guild hopping--a potential bug or the likes--that may cause players to get unearned rewards.
Let me state this very clearly: We are researching this. If you are caught abusing this, you will be banned.
We are fine with guild hopping right now, but we are not fine with exploiting the rewards structure for little-to-no work.
