mosparo

The modern spam protection tool.
It replaces other captcha methods with a simple and easy to use spam protection solution.
FYI: The bird is called Mo (the sparrow).

Spam filters are standard on email servers. There they scan a whole message to detect a possible spam message. Additionally, many settings can prevent spam mail (or at least make them better visible), like SPF, DKIM, etc. But the hard part is that the email is one message, and the spam filter must check the entire message. Since everything is together in one message, it can lead to false detection.

In web forms, the solution is more straightforward: since all fields are separated, we can check all fields separately. In one of the fields, the spam bot has to write, for example, the URL to the website or the message. Because of that, we can execute our checks for the field and detect spam very quickly - if there is a rule to detect spam.

Our target

We don't guarantee that mosparo will catch all your spam messages since the detection is mainly based on your rules. If you set up enough rules, we estimate that mosparo will block more than 80% of the spam messages.

Our main objective is a different one. Firstly, we wanted to create a solution that you can host on your server or web hosting that does not collect as much data as possible.

When we looked for ways to do that, we found that there wasn't a real solution for everyone. Many existing solutions require a puzzle that the user must resolve. For people with disabilities, solving puzzles is maybe not a good way to prove that they are real people.

We have therefore defined our main objective: to collect only data that is necessary, self-hosted, and accessible.
