Jim-san,　I have one question.

I see here,

http://bbon.geo.jp/

It seems that blocked IP have something unique HOST name, like this

163.43.164.69
107.150.34.34
163.43.164.69
210.235.168.236
163.43.164.69
111.70.140.71
163.43.164.69
204.12.239.210

not like this,

KD118152027061.ppp-bb.dion.ne.jp
59x158x28x199.ap59.ftth.ucom.ne.jp
110.227.150.220.ap.seikyou.ne.jp

Can you set traps to these unique HOST name? I think they are maybe crawler from SC.

I think, they are maybe proxy, but I can't burn them by Boo80.

2ch has regulation system for writing, but perhaps don't have it for reading.
Can you enlarge regulation system for not only writing, but also reading?
