But worst of all, there's no incentive to fix it.
Most cases of bad actors on platforms are already a violation of the terms of service. But until it starts to affect the platform provider financially, everyone will keep funneling money in to the problem. The bad actors pay for the ads, they pay for the phone numbers, they pay for Internet access, and thus it's too easy to look the other way.
Then the providers come to us, the victims of the crimes whose time is wasted, whose lives are scammed. They say it's too big a problem, and gosh darn it they just can't do anything. They have their pockets turned inside out and shrug at us like we're supposed to believe them. But it doesn't affect them, it affects us, and they've never cared about us, just our money.
