Testing and knowing all the possible solutions to fight "3rd kind intelligence spammers" seems a little overwhelming to me, it appears to me like the story to search for a firewall that solve every security problem. Indeed just consider that a parameter of curl allow you to simulate any post submission. And the problem eventually could be exactly this, the why of the existance of these advanced clients tools.
