Akismet is a spam prevention plugin from the WordPress author, Matt Mullenweg. akismet�������ʼ�Ԥ����������ߵ�WordPress ���ǹ�mullenweg �� It uses collective wisdom in filtering spams.��ʹ�õļ����ǻۣ��ڹ��������ʼ��� Essentially you, blog owner, help it learn by marking comments as spam.�����㣬�������ˣ��������˽��ǵ�����Ϊ�����ʼ��� It then uses the knowledge to filter spams from other blogs and your too.Ȼ��ʹ��֪ʶ���Թ��������ʼ�������IJ��ͺ���̫�� There are two major problems with this approach.��������Ҫ�����⣬������������

First it can be tricked.���ȣ��������ƭ�� It has been shown that you can mark a legitimate commentator as spam and by repeatedly doing so you ensure that all his future comments are flagged as spam automatically by Akismet.���Ѿ���������������һ���Ϸ�������ԱΪ�����ʼ�����ͨ������������ȷ�����е�δ������������DZ���Ϊ�����ʼ��Զ�akismet �� The reverse is also true.����Ҳ����ˡ� You can manipulate Akismet to mark your spam comments as legitimate comments by repeatedly (as low as 3-4 times) marking them as non-spam in blogs you control and which uses Akismet.����Բ���akismet��־��������ʼ������ۣ���Ϊ�Ϸ������������3-4�������������Ϊ�������ʼ��ڲ����У�����Կ��ƺ�ʹ��akismet ��

Secondly Akismet can be deluged with spam to make it useless.���akismet����deluged�������ʼ���ʹ����ͬ���衣
Akismet flags several proper comments as spam (false positives). akismet���켸���ʵ�������Ϊ�����ʼ��������ԣ� �� It is essential that you sometimes visit the Akismet queue and identify the proper comments and mark them as non-spam.����ʮ����Ҫ������ʱ����akismet���У����ҳ��ʵ������ۺ����������Ϊ�������ʼ��� This helps Akismet "learn".��������akismet ��ѧϰ�� �� This however fails when Akismet catches hude volume of spam comments.Ȼ���ⲻ����akismet���hude�����ʼ���������� It becomes impossible for humans to manually visit the queue and identify false-positives.����ܳ�Ϊ�������ֶ���ʽ���ʶ��У���ȷ�������ԡ� Not to mention the current incarnation of Akismet displays only 150 comments marked as spam, with no paging capability.����Ŀǰ�Ļ��? akismetֻ��ʾ150���۱�ʾΪ�����ʼ���û�д���������

This weekend I received 4378 spams!����ĩ�����յ���4378�����ʼ��� How can anyone check this volume of spam?����κ��˶����ԣ����ڴ������ʼ������� So Akismet stops learning and becomes less useful by the day.��ˣ� akismetֹͣѧϰ����Ϊ���õ������졣 Also some poor commentators are destined to languish in the hell of being marked as comment spammers without any hope of reprieve.Ҳ��һЩ�������ۼ�ע�����ڵ���ı���ʾΪ�����ʼ������ߵ�����û���κ�ϣ��Ļ��̡�

In other words spammers can render Akismet useless by simply deluging the site with large volume of spams.������Ļ������ʼ������߿���ʹakismet���õģ�ֻҪdeluging��վ������������ʼ��� And it works.����Ĺ��̡�

In the end I think Akismet alone is clearly insufficient solution as advertised.�ڽ�������Ϊakismet����Ȼ�Dz����Ľ���취����Ϊ��档 I am hesitant to use Bad Behavior again based on my last experience where it somehow prevented several people from commenting, including my friends.�Һ���ԥ��ʹ�ò�����Ϊ�ٴλ������ϴεľ��飬����ij�̶ֳ�����ֹ���������ۣ������ҵ����ѡ�

WordPress comment spam is in need of a better solution.��WordPress��������������Ҫ��һ����õĽ���취��
