+1 While I personally believe in applying a "nothing ventured, nothing lost" analysis with obvious doorknobs that show up here, nothing excuses breach of contract or any other scamming behavior.
Breach of contract? That's a little over the top isn't it?
Maybe. Not in Ohio, where I am from. Offer plus acceptance plus consideration (which includes the promise to pay) equals a contract. Not performing in accordance therewith is a breach of that contract.
Why? Do you believe that it is OK, or that it should be considered OK, to back out of agreements like the one in this example?
