Please also stop willy-nilly changing the error codes and error
messages.  Since your error messages are so often inaccurate, some of
us have setup special rules to decipher what the errors actually are
-- when you change the text or code, our rules break.

For example, suspended users are/were getting rate limit warnings when
trying to authenticate as them.  Separately, a new "not authorized"
message appears for both failed authentication errors as well as
successfully authenticated users trying friends/ids on blocking
users.  Since the messages and codes are the same, it is hard to
distinguish between these error types to tell the user what is going
on.  There are about a half-dozen of these ambiguities and bad errors
that we've accounted for.  (Don't get me started on "200: OK" non-
errors.)

So, after much trial and error, we CAN figure out the actual
underlying problem based on the action and message you send us.  But
when you suddenly change the error code, or message, it throws our
rules into disarray.

(Of course, it would be nice if the actual error messages you sent
were themselves accurate, but for now we're just hoping you can
CONSISTENTLY send us the same inaccurate errors.)
