While I agree that there is MUCH less of this going on that many think, THINKING there is an issues is as bad as HAVING the issue.
Sure an NOE could run through enough of a CVs dar ring to be spotted and plotted, but few will believe that that is why they were spotted. Far more will believe the "rumor" of spies and second accounts. Rumors of cheating/giving away information can hurt this game just as much as if was really happening.
