Can you tell why evo show in their site those exchangers? Is it the reason that people will start using them by sawing many exchangers in their merchant list? I think they need to monitor their merchants and if anyone do not support them, it is necessary to delete them from exchangers list.
Evo has provided a list of directories where anyone can add their sites if they support Evo in any way, so some exchangers used this opportunity to advertise their sites by adding in Evo exchanger directory.
