Support

If you have a problem or a feature request, please post it on the plugin’s support forum on wordpress.org. I will do my best to respond as soon as possible.

If you send me an email, I will not reply. Please use the support forum.

Translations

Translations can be added very easily through GlotPress.
You can start translating strings there for your locale. They need to be validated though, so if there’s no validator yet, and you want to apply for being validator (PTE), please post it on the support forum.
I will make a request on make/polyglots to have you added as validator for this plugin/locale.

How to choose an antispam plugin

When you look through the WordPress Plugin Repository you will see more than a hundred antispam plugins.
Which one is the best one? Short answer, there is no “best one”. No spamfilter and no method for spamfiltering is perfect.
Slightly longer answer, you could try about twenty and choose the one that fits your needs best.

But there is also a really long answer.
There are different methods that can be used against spam, and every method has its drawbacks.
In my opinion, having a low number of false positives is more important than perfectly marking all spam, you don’t want to miss out on important people or information. Nagging the user in some way has a similar effect, the user might not even want to bother with that and just walk away.

  • Third party services: Services like Akismet, OOPSpam, Stop Forum Spam and also reCAPTCHA offer third party services to check for spam. This can be very effective, but you are giving user submitted data away to these third parties and are also giving your users up for tracking them.
  • Captcha’s, reCAPTCHA and Quizz Questions: You are annoying your users and probably sending some of them away. This especially counts for reCAPTCHA for visitors who have third party cookies disabled.
  • Blacklists: Often running behind the facts. That goes for the way of getting users off that list, and also in getting users on that list.
  • Referer check: check if the Referer header is set correctly. You can never trust it is set correctly. Modern browsers are limiting the use of Referers, though for now that is mostly for third-party domains.
  • JavaScript methods: Spammers often (always?) don’t use JavaScript, they just post the form with spammy data. Drawback for this method is that statistics say that about 1 percent of users has JavaScript disabled. Also, some websites have broken JavaScript, which might make the spamfilter break as well.
  • Activation email for registering users. Users only get activated after clicking a link in an activation email. You still have all the non-activated users in your site however.
