Also, speaking to what happened here...IF the buyer were in fact dishonest (and clever), a seller who knew the escrow.com TOS and remained calm would have a leg up over a seller who got hysterical and stated categorically that he would not accept the return of the domain.
Let's say this happened:
1. Buyer makes payment.
2. Seller transfers (or pushes, makes no difference really) domain to Buyer.
3. Buyer refuses to acknowledge acceptance of the domain and states that he wants to cancel the escrow.
Buyer at this point is obligated by the TOS to return the domain to seller, in order to get his payment refunded. And according to the TOS he must do so within ten business days.
The hysterical Seller raises a fuss, says that he will not take this sh*t, and states on the record to escrow that he will not accept the domain back, that he won't be pushed around.
So...now that it's on the record that return of domain is impossible, that seller will not cooperate with return of domain, escrow has no choice but to freeze funds pending resolution of the stand off. Things could get really bad for the seller if he keeps refusing to accept the domain back; the buyer could sue to get his deposit back, and the domain could end up in a sort of escrow / trust, pending resolution, for who knows how long. Seller, by violating TOS, could end up liable for buyer's attorney fees, leaving him holding the bag with a judgment against him.
In meantime, a clever but dishonest Buyer has use of the domain, and his money is held up, but he knows he'll get the money back eventually and in the meantime has free use of the domain. He might even end up with a judgment against the stubborn seller that will get him his money back, and the domain (the dollar amount of the judgment might end up payable by a writ of execution against the domain).
A smarter, calmer seller whose goal was to get paid for the domain, would never state something as obstructive and violative of the TOS as that he will never accept the domain back. He would just pretend to go along with the process, and then after the ten days have passed, escrow would have to release funds to him, per its TOS. I'm not condoning this sort of seller behavior, but I am saying that calm minds that follow the law or at least appear to follow the law usually prevail.
When the law (the TOS) are on the buyer's side (allowing buyer to cancel), then the seller should be smarter about giving escrow an excuse to freeze funds, or for buyer to sue him for violating their contract.
Cooler heads usually prevail.
