It's easy to have answers when you don't have to really solve the problem, when you actually have to go and fix the problem yourself that's when you really face the problem and those answers are hard won. But I admire those who do tackle such problems or at least attempt too. The cost of real problem solving few will actually try to endure. It's messy, not straightforward and often a compromise you never wanted.
You haven't actually answered anything. You just blurted out things like "manipulation" and "exploitable".
