Contact form spam-protected by additional spam filter

Many visitors are annoyed by illegible letters. Or they enter them, but for some reason they are not accepted.

We free your contact form from this annoying captcha and provide security in another way:

By means of the so-called "Bayesian filter" is used to check how high the probability of spam is.
At the same time, there is a fill-in field for the spambots that they are not allowed to fill in. Humans do not see the field.

At the beginning - in the first weeks - you have to "learn" the system in the admin area.
This means that the contact attempts are listed and you click on "Spam" (unwanted) or "HAM" (wanted).
