Lack of response is due to the jaded nature of what little playerbase remains after constant screw ups on Ncsoft's part. Ncsoft has never been effective at bot control as they refuse to invest the time/money required to do so. Instead they like to rely on useless "bot detection" such as gameguard which just creates vulnerabilities in your computer. It's cheaper/easier to do that than to say pay a couple GMs to head out on the servers for a few hours each to ban obvious bots.
At this point I'm pretty sure Ncsoft is scared to have an actual effective anti-cheat team as they know it would catch a whole bunch of whales.
