Inaccurate. It's not considered a sex crime, but I'd there is an attempt rarner money, it absolutely can be litigated in civil court.
3 problems. You have to have the means to pursue a suit. You have to be willing to be a plantiff and many people have a share time admitting publicly that they got conned by a grifter (look at MAGA). 3. You have to prove to legal standard that the defendant knew she wasn't pregnant or knew the child wasn't yours. That has the exact same problem date rape has. He said/she said about an intimate situation that there were most likely only the two partiee involved. And men have no banked credibility here because of the NUMEROUS ways and history of abandoning their legit children and wives and dodging child support they, as a group, are notorious for.
