Weird Reason to Turn Down Candidate

I am sourcing for this company, and they turned down one of my candidates for some very valid reasons. I was a bit shocked, however, to see that this candidate's history of relocating for a job was held against them. It felt very strange to add when they had other, more valid reasons to move on. As a whole, I really dislike working with this company, but they are my agency's bread and butter. I am a little wary of how they hire and I do think they have acted discrimantory in other roles but have used all the right language to get around it. Anyway, another day on the grind ig.
