Extension:Check Spambots/check spammers plain.php

This code is from it-mate.co.uk (check_spammers.zip v0.39 29/09/2009) and contains one minor patch, to disable any direct output to the screen unless a spambot is detected.

It looks for a configuration file (config.php) in the directory in which the extension code has been installed. See Extension:Check Spambots for full installation instructions.
