False accusations happen on an almost weekly basis, not all go through the courts.Yeah I'm aware and take the point. It's kind of why I called out a seemingly alarmist statement.
Most false accusations go through to tried and true method of going to social media and releasing a statement which is guarantees to affect the accused's life negatively regardless of evidence or lack thereof. The simple tactic of throwing a statement out into the ether will harm someones life and reputation before any actual facts come out.
Also, not all accusations are rape. Sexual assault, harrassment etc have the same result - you're a pest, pervert, should be fired, jailed, harrassed, doxed etc.
