It sounds to me like a primary use case of this would be... cheating...
Unlike other dating platforms, this one is integrated with your supposedly up to date profile. Being able to set up a low risk secret crush with a known friend seems likely to be popular to those interested in doing so.
That is to say, a person who wants to cheat has no problem having a Facebook profile, so there’s not a need for anonymity against being found by known acquaintances like you might expect on other platforms.
