Testing many domain referral spam options I finally found a method that universally addresses the ghost spam in Google Analytics in a simple but effective hack.
Ghost referral spam in Analytics for the uninitiated is a "fake website hit" from a spam website that hit's Google analytics but never actually hit's your website.
The problem is that Google Analytics displays this as a visitor from a particular spam domain, skewing your website traffic data.
The suggestions I have seen thus-far to counteract this include a list of spam domains in a filter. Which is messy and buggy.
This method target's unset device screen sizes.
Bot's are not browsing as users would, they simply hit the Google Analytics tracking with a referrer and go away.
Henceforth, forthwith, if you filter out unset browser sizes you filter out ghost spam bot's and neatly clean up Analytics data without having to maintain a list of spam domains.

There's your Analytics p**n update for the week.
There’s been a lot of talk recently about referral spam and how it’s ruining everyone’s analytics data. While this isn’t cause for panic, it is very annoying, and depending on the size of your site it could be having a very meaningful effect on your data.
