I think the reason for this is that the Ancesteral Community Tribe will be cancelled and this one is taking it's place. That tribe was mostly a bunch of bitching and complaining and this tribe is it's sister tribe, the positive and more edifying tribe.

I am not sure if that answers your question, but there is my answer. So if you are a part of the Ancesteral Community tribe then these alerts will replace them, if not then I think you may be getting another one from this tribe.

But I think what is happening is that the person posting the alerts is posting them on multiple days and that is why you get so many alerts, it's not the tribe's that are doing it, it is the promoter that is doing it and their friends.
