The best Joomla spam prevention extension

OSpam-a-not Joomla spam prevention extension OSpam-a-not is the easiest way to protect your Joomla site from spam bots filling out your forms. OSpam-a-not uses a clever and unobtrusive technique to protect your forms from a flood of spam.

We created OSpam-a-not because we needed better Joomla spam prevention. We use OSpam-a-not ourselves, so we maintain it and update it regularly. Like all the other Joomlashack products, its is easy to use and set up.

The main Joomla spam prevention features


Joomla spam prevention extension

OSpam-a-not works immediately after install

OSpam-a-not works without the need of any extra setup after install. However, you can enable the recording of spam attempts and set a minimum form time in case form submissions are blocked too quickly.


Joomla spam prevention that simply works

You don't need a captcha system. OSpam-a-not protects your forms against spam.

Joomla spam prevention settings

How does OSpam-a-not's Joomla spam prevention work?

OSpam-a-not uses a Time Gate. This is a hidden timestamp that records how long it took to fill in a form. If the form was submitted more quickly than humanly possible, we can block the submission.

OSpam-a-not also uses a Honey Pot. A text field is added to the form and hidden by adding a style tag at the end of the document head tag. It isn't visible to a human user, but a spambot doesn't see that and fills in the field anyway. If we find anything at all in that field when the form is submitted, we've caught a spambot in the honey pot! And the form is blocked.
