As part of the onboarding process, the worker will perform sample services. We will pay them for this (along with referral fees if they were referred). Having sex with people is what a sex worker's job is. It's just that the client in this case will report to us and verify their ID.
Seems like a good way to filter out people that are not serious or have ulterior motives (such as law enforcement).
For a start, if soliciting prostitution is illegal, the LE agent doesn't have to perform service, they just have to bust the “client/screener”, and turn them so that they report back properly.
And in the end, what does LE end up with by doing all this? A few individual prostitution "busts", with no real change.
But that only works if the client/screener can actually lead you anywhere.
Note that a similar technique also works for criminal gangs interested in robbing Johns who want to exploit your platform for their funnel.
