Neither manual sifting nor JavaScript querying would filter out registered users a priori. For a JavaScript query, you could filter the results based on username before they're displayed, though.

Any username which matches the regex  is guaranteed to be an IPv4 address, even though that regex is a horrible test for IPv4 addresses in general. I've never seen an IPv6 address in any history, so I don't think you need to worry about those atm.
