Reporting people to dodge self accountability is a common impulse yes. But this gums up the overwatch system with genuine players having a bad day, and it also dilutes the hit real toxic people and griefers ought to take.

Pre-modern societies used to punish false accusations, and for good reason. And it worked.

Shame, public ostracization, damage to one’s own reputation, fines and even death. There was a time when crying wolf was a punished severely.

Perhaps dota could take a page from that book? For example if they make 10 report that all come out as innocent in overwatch cases, in a row, then some form of action is taken on them and they receive a warning in the inbox. 10 is hypothetical but I’m sure some machine learning optimized way to deter false accusations can be thought out.
