I'm so glad this change has finally been made, but there is only speculation on the new mechanics that these bans are based off of. The dev team should at least give an idea of how these mechanics work so there aren't cases where people are wrongly banned/dev wiped.
Don't go under the mesh and you won't get banned for going under the mesh.
As an addendum, don't have people in your tribe go under the mesh either and if you can't stop them from doing it you should cut those ties before they drag you down with them.
