 server1.xpressaccess.comがフォームを取得した後、OpenProxy経由での書き込みを試みている様子がはっきりとわかる。
 対象BBSは、DSBLに登録されているホストには問答無用で404を返すように改造してあるので、投稿自体は失敗に終わっている。
 しかし、司令塔みたいなserver1.xpressaccess.comはDSBLには登録されていない。ただの想像だが、DSBLとかに登録されないように運用しているのだろう。BBQでも引っかからないし。で、潰してもいい人様の穴のあいたマシンを踏み台にして、実際のspam投稿を行う、と。


 以下は、他にもあった同様の痕跡。
