>>472 is the person in charge of advertising posts blocking (Rock54 system) for 2ch (as well as bbspink)
He worries that there are lots of Child Porn DVD sales site ads in 2ch posted and its log says its hostname is "PIE.us" and worries about PIE server is used as zombie bots or someting.
I personaly think that one of your rental server user (which does not set reverse DNS lookup) hosts proxy server and posts these ads to 2ch though.
If you would like to obtain more information for tracking the offending user, please anchor >>472 and ask for it. (I will translate it, if needed, too.)
>>477 pie.us does not have any other sites on it. Maybe there is a dns problem? The person in charge of rock 54 is not in charge of advertisement on bbspink. Are you talking about blocking spam advertisements?
>>478 Rock54 system is the way of kicking advertisements as much as possible for 2ch/bbspink. The person in charge of Rock54 system receives reports at below thread from 2ch/bbspink users and register the new advertisement to Rock54 system.
So, it is not just for 2ch. bbspink receives the benefit as well. Rock54 system keeps logs of the registered advertisement for blocking purpose. And the person in charge of Rock54(>>472) finds the hostname "PIE.us" from the Rock54 logs and asked about the possibility of zombie bots inside the PIE.us server.
>>479 Oh, no it is not that. The default dns for those ips the servers are in is pie.us. Nobody every changed it. That is the ip that the 2ch server is on. He is seeing the 2ch server in the logs. Yes, I understand spam advertisement. There is an official advertising agency that is taking care of the ads on Bbspink. Hopefully they will be able to sell all the advertising spots. It is a real help. http://bbs-ad.com/
>>481 IP ranges 206.223.144.0 - 206.223.159.255 belong to the NT Technology and some of these IP addresses points to "PIE.us" hostname. If none of them are used for rental server and its security are solid enough, it might be because the spammer set the false reverse DNS lookup info on their DNS server.
