Akismet is an advanced hosted anti-spam service aimed at thwarting the underbelly of the web. It efficiently processes and analyzes masses of data from millions of sites and communities in real time. To fight the latest and dirtiest tactics embraced by the world’s most proficient spammers, it learns and evolves every single second of every single day.
Example: “I’ve been using Akismet for more than four years on several web sites and Akismet caught countless comment spam.”
According to Wikipedia, Aksimet attempts to filter link spam from blog comments and spam trackback pings. The filter works by combining information about spam captured on all participating blogs, and then using those spam rules to block future spam.
Akismet is one of the largest and effective anti-spam filters. According to Akismet’s blog, in October 2014 they saw over 400 million spam messages come through per day on 12 different days. There was a rise of 44% in the number of spam comments caught from September and a 185% rise from last year in October. In total, Akismet caught 11,337,365,500 spam messages this month, and 207,939,000 ham messages. As usual, the amount of legitimate messages going around is much less than spam – coming in at 1.8% this month.
While there is high praise for the results and effectiveness of Akismet across the globe, there is also some data that indicates up to 10% of the spam comments it catches can be falsely identified as spam, when they could actually be good comments. Akismet is constantly learning and the developers are providing updates as data is complied and validated.
Although Akismet comes pre-installed on all WordPress sites, it is not automatically activated. There is a free version and business and enterprise versions that require a fee. It is best to look at the options at the available plans in detail and then if you have any questions as you are activating your Akismet to free yourself of the irritating and time draining realities of spam comments, see the step-by-step walkthrough.
