In an effort to prevent ghost spam, I am trying to filter traffic by hostname in Google Analytics. I have found several hostnames that appear legitimate, and now the length of these hostnames in regex exceeds the character limit in the Google Analytics filter field.
When I try to create two separate "include" filters (to cover all of these hostnames), they conflict with one another. As a result, my view doesn't register traffic from the set of the hostnames included in Filter 1.
Is there a way to "include" all of these hostnames regardless of the character limitation?
Is there a central repository of "safe" hostnames? I've got www.mysite.com, mysite.com, and subdomain.mysite.com. I've also added translate.googleusercontent.com|webcache.googleusercontent.com|web.archive.org|mysite.com.googleweblight.com|translate.baiducontent.com| mysite.us1.list-manage1.com|ww.mysite.com|www.mysite.toolweuse.com
