Those with admin privileges can adjust the spam score to their liking.
Click on the “Settings” icon in the left sidebar - the last one from the top, and select the “Spam Settings” settings at the top of the page.
There, in the “Importance” column (see screenshot below), you can adjust the value to be added to the spam score of your results, for each individual factor. You can set the sliders to any value from 0 to 5, designating how important you consider each factor to be, and change the values for certain factors, for instance, how many characters or hyphens are you prepared to tolerate in a URL that is to be returned as a result.
