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 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.
- 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.
You could have a bright idea about combining several methods, but then you get the drawbacks of all the methods you use.
Another complication of choosing a good plugin is that most antispam plugins don’t tell you what methods they use. The documentation doesn’t tell you, and looking at the source code just leaves you confused at the chaos that it often is.
This plugin is compatible with ClassicPress.
This plugin is also available in GitLab
- Install the plugin through the admin page “Plugins”.
- Alternatively, unpack and upload the contents of the zipfile to your ‘/wp-content/plugins/’ directory.
- Activate the plugin through the ‘Plugins’ menu in WordPress.
- That’s it.
The plugin itself is released under the GNU General Public License. A copy of this license can be found at the license homepage or in the la-sentinelle.php file at the top.
Why is there no “best” or “perfect” antispam solution?
Spam is a social problem, while antispam solutions are technical. There is no way that a technical solution to a social problem will have a 100% perfect match ratio on spam with a 0% perfect match ratio on real messages.
I get false positives
You could go to your form page, right click on the page, select “Inspect Element” > Console-tab. Reload the page and see if there are errors in your console.
I am being targeted by a spammer
That is unfortunate. The default spamfilters in this plugin only protect against general spambots that are targeting any form on any website.
First thing you can do is enable the ‘Stop Forum Spam’ spamfilter, that should help against most human spammers and targeted attacks, though only for default forms in WordPress Core.
If that doesn’t help, I advise to add an extra plugin in the form of OOPSpam, that should provide a good defense against human spammers and targeted attacks.
