Imagine a situation like this...
Someone on a random guy's team was feeding. In the post chat lobby, the guy asks everyone to report him. Another guy speaks up and says asking for reports is reportable and so asks everyone to report that guy for asking for reports. But another guy says that asking for reports is reportable and so asks everyone to report that guy for asking for reports for that guy asking for reports. But another guy says that asking for reports is reportable and so asks everyone to report that guy for asking for reports for that guy asking for reports for that guy asking for reports. This goes on and on between the ten people, with some asking for reports more than once.
In the end, who gets banned? 0_0
