You can be arrested for a crime that you know nothing about. Or even arrested for a thing that wasn't a crime, but the police just wanted you to have a bad day, so they charged you with something they knew couldn't stick. Yeah, that's illegal, but what's anyone going to do about it, sue?
But if you said something on twitter, or were caught on camera doing something repugnant, there's not really much plausible deniability.
When it comes to things like sexual harassment, where there's no direct proof, people generally get the benefit of the doubt a few dozen times.
I'm not even saying the double standard is all bad but I really think that is a stretch. Plenty of people have been caught in situations on viral videos that were taken without their knowledge that show an incident without context.
Additionally - everything you could say about police making up incidents on a report is the same for someone being sued re: harassment or whatever. If you are suing for legitimate issue X, any lawyer will tell you to play up additional incidents that will look bad in the press even if you don't have evidence for when it would go to arbitration/trial.
