Let’s assume that people massively want to cheat (unfortunately, they don’t, and a lot of people die because of this); let’s say 9 people on 10 are cheating. Are you okay to discriminate one handy because you don’t want to be scam ?

You just making him/her pay because of your ego. To rephrase it : one many disabled people are you okay to discriminated because you don’t want to be scammed ?

Okay let’s levelup; if someone is cheating, maybe this one has a better idea of the reason he has to do it than you are.
