Having false positives in a public accusation would be a disaster for everyone involved.
Additionally, a list that is private creates far less incentive for any malicious/spurious additions.
A private list seems far more practical, sadly.
And I really don't agree with the sentiment that a few false positives are OK in situations like this where lets face it accusation = guilt. We don't operate like that in any other areas of criminality and for good reason.
We've been through months of "evidence=impunity". Partygate. Braverman getting sacked over a "but her emails" incident of deliberately leaking classified material and then getting reinstated six days later. Gavin Williamson. And much of the misconduct isn't actually illegal! It's just misconduct and intra-party bullying.
The problem is there's no "adults outside the room" you can call on to make a determination. It's only a political system, a set of interlocking popularity contests.
It's all fun and games, until you end up on the false-positive list. You get blackballed all the time, you career stops, you can't get things through, just because someone thought something and spread rumors, you don't know why, and can't do nothing about it.
No, it's rape and sexual abuse.
No more fun and games for you... and good luck proving you're not a rapist or a sexual abuser, since it's an unofficial unwritten list, spread by word of mouth.
I do not get the impression that any women would trust you with access to any such list, or would rely on you for such information.
Mainly because you seem extremely worried about ending up on such a list, and do not appear in any way to be concerned about the women trying to protect themselves.
If someone did something, they should be punished... we live in an era, where everyone carries a camera with a microphone in their pocket, and proving stuff is easy now. Noone should have the power to silently fuck with someone, because they want a promotion, that the falsely accused would otherwise get.
His lawyer was filmed trying to take of his pants on a bed in a hotel room with a woman he believed was an underage girl and nothing happened.
I certainly won’t shame these women for talking to each other about what men to avoid.
Given that it is impossible to outlaw rumors it is ultimately up to those in power to ensure that reporting misconduct via the proper channels is more effective than relying on private lists. Given how many people feel unsafe with members of Parliament it is unsurprising that they resort to alternatives to keep themselves safe.
