Ironically enough this is true for most foidlets, the amount that I've seen that claim to be femcels but utterly refuse to use dating apps is absolutely hilarious. They know for a fact that they could easily get thousands of orbiters without trying, but they'll use every excuse under the sun as to why dating apps are illegitimate sources of relationships. Meanwhile your average guy is just trying to get literally anything he can from anywhere.
That's probably why you mainly see femroaches as the ones who tell people something along the lines of 'dating apps aren't real life!!' or 'dating apps are shallow' whenever they're trying to disprove inceldom. Of course, the claim itself is ridiculous considering that dating apps are literally how the majority of relationships start now-a-days (and is only going up over time), so them being shallow is just a natural mirror of how women really act when they have options.
But for femroaches themselves, they don't even have to use dating apps if they don't want to. Some roastie I was arguing with was trying to downplay my inceldom by telling me that she was also ugly and supposedly treated poorly by guys while in high school—but she later admitted she had been in multiple relationships and had broken up with the guys for various reasons. What a whore, LMAO.
