But it isn't nonsensical: filtering your client base into qualified leads is sales 101.

You wouldn't advertise tax law services to 100% of the population. Nor would you want to high touch sales on 100% of the population for a sex scam.

I'm sure some amount of it is explained by incompetence, poor english skills, etc. But if that was a real detriment to sex scamming, it would have been worked out of the market.
