Ms Siobhán Cummiskey:

It is not necessarily five and differs in different circumstances. A known terrorist, for example, would be removed immediately without any strike. In some cases, if a person uploads child exploitation imagery, it is one strike and he or she is out. There is no one or set limit for how many times a person can violate the policy. It depends on the nature of the violation. An egregious violation can result in a person's entire page or profile being removed.
