For anyone that is interested in trying to eradicate these AI bots from PSO2 , can do at least the following:
PSO2AH is a CHINESE based website, however I did find that its currently being hosted by GODADDY.COM If you feel the need to send GODADDY an email, you can at : abuse@godaddy.com.
So, I bet at some point if GODADDY.COM receives enough complaints, PSO2AH will be taken down.
If you Want to see for yourself who is Hosting PSO2AH goto LOOKUP.ICANN.COM and search for PSO2AH and see for yourself.
