Strangest Spam Report

I guess cries about spam are reaching new levels of absurdity. Today I received a warning about a spam-report... from an article responder! This is just a autoresponder setup to send an article, when a user requests one. It does not (can not) send mass mailings of any kind, only respond to an e-mail. Yet someone said it was spam... A number of my articles have always been available using this method. Some ezine-directories even insist on it. As from now - this has stopped :(
