However, on a whole, it is not advisable to take such a strong stance on something that clearly has a potential for false positives. Many of us using the Declude JunkMail system have actually decreased the weight of SpamCop over time because of clear problems that have been found in listings. A stance of "If it is listed, I am going to block it outright and let their admin worry about it!" is not going to sit very well when a CEO or accountant is waiting for a critical e-mail that is coming from a company who's e-mail server may get temporarily listed do to an error or misconfiguration or unwarranted report. In any case, posting such a hard ball stance on an open forum does more harm than good to those that may read it who already do not have a good understanding of the thought process behind such decisions and who say hey, I am going to do that too and then are left scratching their head a week later wondering how come I am not getting that e-mail. After all, how does a reader know where the poster of that stance is coming from, ISP, corporate, Education or what not.
