Some fraction of applications that don’t really fit are submitted by people trying to keep their unemployment benefits. You have to keep applying to continue to qualify, but the jobs don’t have to be a perfect fit.

Being unemployed is hard and can be really demoralizing. Try thinking “I’m probably helping someone pay rent until they find a job listing that works for them” when you’re rejecting obviously unsuitable applications. It at least makes the “wtf”-ness of some of them seem a little less weird.
