Finding men who say they are poly, but really just want FWB

I have been polyamorous for over a year. Several months of that I was married, and I have been solo poly for the majority of it. I find within the polyam community near me, there are a lot of very conscientious and kind people, but what I have been noticing a pattern of is men explicitly saying they are polyamorous and the values of polyamory align with them, but overtime I find out they don’t actually want any kind of attachment or true connection (I ask a lot of questions upfront, and either they are outright lying, or they answer very misleading), they want casual, somebody who cares about them and checks on them, and is fun when they want it. That’s friends with benefits- not polyamory. My heart is bruised and I’m trying not to just give up on Polyam. I’ve only used the Feeld app so far, as I live in a small county and it’s hard to find folks in my own county.

I don’t know what I’m looking for exactly here, maybe solidarity, I’m open to advice about how to avoid this continually happening, etc.
