TODO: What is an attacker figures out a way to keep on querying the accumulator manager for acceptable elements. Like submitting add or remove requests and keeping track of when errors were returned or requesting witness for elements. In practice this would be a cost to an attacker but still something to be aware of. Check if element is part of the initial elements. Such elements should not be add
