Spam: how to filter out direct website visitors from Ukraine and Germany

[MarketingRumors]

Hi there, I was reading this article: https://moz.com/blog/stop-ghost-spam-in-google-analytics-with-one-filter as I am experiencing a lot of visitors from Ukraine and Germany as direct website visitors with only 1 pageview, a huge bounce rate (of course) and little time spend, so I am convinced its spam.

In the article, it explains how to find the hostname to set up a filter but if I do so, I see that the highest amount of website visitors with this behavior come from the hostname that has my own domain name in it, so I can't exclude this. What should I do?
