Tired of running around to cancel spammers messages since I setup the feature of comments on this site, I decided to reinforce the filtering policy and to setup an automated filter. For that purpose, since I use WordPress, I chose Akismet whose operation is very efficient. The vast majority of the SPAM is simply detected. Some (those where Akismet is not certain) end up in the moderation queue – I must give my own advice. Recommended to fellow bloggers.
