I am having massive spam traffic issues on the website, with a huge portion of my traffic in GA coming from spammy sources. I keep excluding these sources via filters I have setup, but how do I go about removing it completely and not seeing this again?
It's really frustrating and causing massive problems with data accuracy.
The best way to block referrers from accessing your site at all is to block them in your .htaccess file in the root directory of your domain.
