Spam protection check

CZ   EN  
There is a number of spam robots on internet that scan web pages for comment forms and if they find one, they try to post a spam message (for example link to some unrelated page selling medical products). To protect against these robots we use simple text spam protection (or CAPTCHA, read more on, which should stop at least some of them.

This protection currently only applies to unregistered users and only when posting first comment or first comment after longer delay.

To pass the robot test you need to transcribe a number displayed in verbal form as the numeric character, for example, six as 6.

This test is placed in forms for sending messages to users, forum and comments to pictures and taxa, species mapping and identification of images, all of these being functions accessible to unregistered users.
