we see tenants trashing houses because they signed a lease, couldn't afford to pay the rent then blame the landlords for renting to them. How dare someone have a house and I have to rent from them!! Trashing a house is breaching a contract and a way of "getting back" at what some people believe is unfair! All above is very similar!
So a tenant trashing a house causing financial loss, stress and hardship to the owner is comparable to average Joe tactfully (although illegally) advertising his private sale on re.com... in turn saving thousands of dollars in commission from the greedy paws of an agent? sorry, I don't see the similarity there.
