Don't base your app on the assumption that it is 20,000 calls per hour
per user.

You get 20,000 GET calls per whitelisted IP address, period. It does
not matter if you use those calls for one Twitter account or 10,000
Twitter accounts.

If the API is currently behaving differently, then it is a bug.

I have had discussions with Twitter engineers about this, and the
intended behavior is an aggregate 20,000 calls per whitelisted IP
address as I mentioned above.
