The rate limit can be made more flexible or switched off on request.
However, before that I suggest you look further into the design of
your app.
Firstly, you need to look at why your app was sending an identical
setLocation once per second. Was this purely for testing? If so, fine.
I would have thought your app would update a person's location only on
significant change in position and that API calls to get people's
location would be more frequent that setLocation calls.
I'm sure other members of the Rummble team may have further
suggestions for you.
