My take on latency in general is this: You may just use the API to flag (not act) in an async way. This way, you can just alert/monitor and decide later whether or not to take any actions while keeping the flow non-blocking. Another approach would be to run it against existing handles to see what opportunities exist (ex: premium usernames, impersonators etc.).
Sounds like a good opportunity for some kind of batching feature.
