I guess the lawyers wrote this draft as an extension of the modified Twitter TOS.
Alex, you will need to jump on this draft from a dizzy height and get all your Platform rules in there. Once the API Rules are published as "The Rules" you will have no grounds to blacklist an application for other than what is written in "The Rules". Unless the rules also state that, "we can blacklist an app for any other reason as we deem fit," which will fly like a lead balloon. If the rules are not clear and comprehensive, they will become a ball and chain around the ankles of the Platform team. Dewald
