Abusing the cancelation policy is the specific immoral act I'm calling out here. Offering employment invitations is fine.

But, often a company has very forgiving cancelation policies to be customer-friendly. By abusing those cancelation policies to do a DDOS-style attack is going to lead to adverse impacts on the ecosystem (less forgiving cancelation policies, drivers & riders wasting time chasing bogus reservations, etc)
