False Negatives and False Positives are always connected. On the other side of the equation, there are plenty of bad actors who will casually flag their competitors to score a quick win. Crime doesn't like to go uphill - raising the stakes for feedback lowers the prevalence of bad actors.

I think that's a different issue. Amazon has thorny problems with takedowns. Company A trying to get rival company B's listing taken down probably happens 100's of times a day. I believe Amazon uses "proof of purchase" kinda like a CAPTCHA or proof of work - an extra hoop to jump through to reduce the volume of these things they have to adjudicate.

It should be a term of service that you’re not allowed to interfere with other customer’s listings.

If I found out one of the tenants on my multi tenant system was trying to mess with another’s, I would be livid.

CRM should never mean Sales Prevention as a Service.

The great thing about filtering is that you don't have to hear the screams.

These accidents play out in slow motion until someone corners you at a family reunion and asks why their friends can't create accounts and when you ask them how long they say "months".

You'd think... but in a growing b2b company, the CRM is where sales get prevented under a certain threshold. heh.
