No. If the system is truly anonymous, then people outside the team can submit reports. Continuous accumulation would not indicate there is probably a problem with the accused, given the motive and opportunities for abuse of the reporting system.

Elsewhere in this thread the difference between anonymous and private is discussed, along with semi-anonymizing strategies for achieving privacy protection, which I believe would be helpful for the outcome you describe.
