RECO needs to arrange to have the practice prohibited as quickly as possible.  There's more to an offer than price, there are conditions, closing date, etc that can affect price offered and the Seller's decision. So for example, if I submit a clean offer, i,e, no conditions, but my offer is less than an Offer that had Conditions, who is to say that my Offer is not worth more to the Seller than the higher priced offer? 
As a buyer I would never include the Escalation Clause.  In today's market I would have a clause inserted in the Offer protecting me in the case of competing offers, where some of or all of the competing offers never materialized.
