Recently I am getting some referrals traffic which are everyday changing their name (I am blocking them everyday from GA). First few days their name was example.xyz but now they are using various name. All the traffic's are coming from Russia. They are only landing to / and nowhere. How can I identify that it's a spam traffic or not?
Just add a hostname filter, this will block 90% of referral spam which won't originate from your own server hostname (yoursite.com).
