Here's a wrinkle.
I maintain the server on which my 1.2.14 version board is located, but I only have moderator status. I too am having this porn bot problem, and my admin has also apparently gone awol. Does my access to the server give me any added ability to obtain admin status so that I can end the porn bot problem?
I'll be honest; I can't figure any of this stuff out (which is why I wasn't the admin). If someone could help me, I would greatly appreciate it.
