Akismet Anti-Spam


Akismet verifica els comentaris i enviaments dels formularis de contacte amb la nostra base de dades global de brossa per protegir-vos a vós i al vostre lloc web de contingut maliciós. Podeu revisar la brossa dels comentaris que atrapem a la pantalla d’administració “Comentaris” del vostre blog.

Les funcionalitats principals de l’Akismet inclouen:

  • Comprova automàticament tots els comentaris i exclou aquells que semblen brossa.
  • Cada comentari té un historial d’estat, per tant pots veure fàcilment quins comentaris han estat detectats o eliminats per Akismet i quins han estat classificats com a correu brossa o com a no correu brossa per un moderador.
  • Les URLs es mostren en el cos del comentari per revelar enllaços ocults o falsos.
  • Els moderadors poden veure el nombre de comentaris aprovats de cada usuari.
  • Una funció de descart que bloqueja totalment la pitjor brossa, estalviant espai en el disc i accelerant les actualitzacions del lloc web.

PS: You’ll be prompted to get an Akismet.com API key to use it, once activated. Keys are free for personal blogs; paid subscriptions are available for businesses and commercial sites.


Upload the Akismet plugin to your blog, activate it, and then enter your Akismet.com API key.

1, 2, 3: fet!

I have used Akismet for since my first site 10 years ago. This has been by far the best anti-spam fighter I have used. I keep it even in conjunction with other protective software without conflicts. Try it, you'll like it. Very inexpensive to purchase. Easy to set-up.

Have only been using this for a month or so on our test wordpress site. It does catch some basic spam comments and form submits, but in general it does not stop most bot-spam from filling out our forms. We've had to add captcha which made a much larger dent in the volume of spam but even the combination of the two is not stopping all spam, maybe 85% of it.
