I wanted to add some more information to this that may be helpful. There are third-party services that can be used to prevent bots from being able to use APIs, and they are supposedly pretty good from what I understand. So if this proposal passes, the plan would be to use one of those services in front of the battle API for modern format battles and the Splinterlands team would not be spending any resources "policing" the system or trying to identify bots and things like that.
If this initial trial is successful and we continue this on an ongoing basis, I would probably make a proposal to ask the DAO to help cover the costs of that service, but we'll cross that bridge when we get there.
