There are posters who disagree with me in intelligent ways. There are posters who disagree with me in interesting ways. There are even a few who manage to disagree with me in intelligent and interesting ways....but also people who chronically do neither and somehow manage to not even be comic relief.
Now, some forums have an option to filter posts from specific users. Works great on chronic spammers too; you see it a lot on forums that are more self-regulating because it also tends to quiet down feuds between people who just can't get along.
Just suggesting a feature that Volconvo might consider.
