Obviously, the very first requirement is to have a secure hosting platform and is always a good idea to use a reliable security plugin too ...
Usually, a good security plugin not only protects your website against malware and trojans, it also blocks referrer spam.
If you don't have a dedicated security plugin that can handle these issues, you'll have to find a way to solve the problem ...
And there are two ways ...
Method #1: blocking referrer spam in WordPress using a plugin
As you can guess, there are several WordPress plugins that can help you keep referrer spam to a bare minimum.
Usually, these plugins use web services that are actively monitoring referral spam websites and use that list to block referral spam.
I recommend you WP Referrer Spam Blacklist for two reasons ...
First of all: is pulling it’s 500+ blacklist from the community-contributed list of referrer spammers maintained by Piwik, a leading open source web analytics platform.
Second: there is no need for configuration. The plugin runs in background redirecting the referral spammer to a blank page.
In other words, all you have to do, is to install and activate the plugin, and you're done.
Here it is:

OK. Let's move forward to see the second method ...
Also today I deactivated G+ from my "Sociable" list in WordPress because I kept getting Warnings from google that I was spamming each time I wrote a post and hit the G+ to post it to Google+ I surely don't want them to cancel my google account. I have had it for many years. If you have any thoughts on that subject I would appreciate it also!
Great training.
