ORDBが年内で停止

「近年spamerの戦術が変わってきており、RBLが有効ではなくなっている」とも書かれてますね。時代の流れなのか。。。

We regret to inform you that ORDB.org, at the ripe age of five and a half, is shutting down. It's been a case of a long goodbye as very little work has gone into maintaining ORDB for a while. Our volunteer staff has been pre-occupied with other aspects of their lives. In addition, the general consensus within the team is that open relay RBLs are no longer the most effective way of preventing spam from entering your network as spammers have changed tactics in recent years, as have the anti-spam community.
