We apologize for the instability of composr.app and appreciate your patience. We are working on the statistics addon and trying to find an optimal way to store and render data. Unfortunately, we have yet to find a solution that can handle the traffic (and therefore, tens of millions of statistical records) of composr.app. We're working hard on one.
If you last had session activity within a few minutes before, we can detect if the IP address geolocation is more than 50 miles away of that, and then block it.
1) Stopping hackers
2) Stopping sharing of access to paid sites
For case '1', we'd probably want to allow the user themselves to unlock the new access.
For case '2', it is more of a case of the user being given the option to dispute the block, and the staff an ability to grant a login extension.
