As Vilify mentioned, this is not practical, and won't solve a majority of the scams that are occurring.
However, we do have something that will help tremendously! Please use the Request Mediator link in your topic. An overhaul of this feature was finished from the front to the back that makes it much easier to use, and wait times are significantly less. Since it went live last night, the average wait time for a mediator to accept your mediation and get it started has been under a minute!
You can help by letting others know about this as well, until we announce this more globally sometime later today.
Thanks
