It should be acceptable but if you want to add a clause holding Sunken Stone responsible, we are going to have to add another sentence along the lines of “Amazon is unpredictable and products and accounts get suspended all the time. We’re going to use our best efforts to prevent this and help you if this happens”. The reason we need to add something like this is that things go wrong because of Amazon all the time. So we just want to naturally prevent being sued if it’s Amazon’s fault.
