I'm no lawyer, either (nor am I ANAL), but I think you're correct. In addition, I believe the FTC only really has jurisdiction to intervene here if it believes actual consumers are being harmed by plentyoffish making the claims they are. Since it's a free site, it seems unlikely anyone's being harmed by anything plentyoffish is doing, except possibly for some wasted time. And, in this respect, I'm sure plentyoffish is no worse than a lot of other time-waster web sites.
