Unknown spam traffic in Google Analytics and how to deal with it?

Question

Google Analytics

Hello!
Probably many people have already encountered this problem, in the GUA there was an unknown spam traffic like get-free-traffic.com and event-tracking.com. ... How to deal with it? Is it possible to delete, block somehow?

Answer 1

Simple answer: no way. Hit him.
Difficult answer.
First, this is not real traffic. Nobody visits the site. Spammers simply exploit a hole in GA that allows you to send data to your account not only from your site, but also from another server on behalf of yours.
You can catch and filter them one by one, but you'll get bored.
Secondly, we hope GA developers will solve this problem soon.

Answer 2

In 2 steps:
1. Create the following filter : joxi.ru/XEA4vBBivd8Gmb
This is the expression in it:
floating-share-buttons.com|social-buttons.com|simple-share-buttons.com|free-share-buttons. com|free-social-buttons.com|Get-Free-Traffic-Now.com|event-tracking.com|r.duckduckgo.com
This removes data since the filter was created.
Old data can no longer be cleared from this spam.
2. Therefore, we create a segment that shows traffic without this spam.
So joxi.ru/4DmBDBBCgXnyAP
And there we specify again: floating-share-buttons.com|social-buttons.com|simple-share-buttons.com|free-share-buttons.com|free-social-buttons.com|Get -Free-Traffic-Now.com|event-tracking.com|r.duckduckgo.com

Filtering is good, but they change domains all the time. For example, now I have a new year.rf and traffic-cash.xyz. They, of course, can be added to the filter, but new ones will soon come.
And does it definitely go through a hole in Analytics (in the sense - directly winds up data in Analytics)? It seems to me that it is much easier to send bots to sites that will generate traffic, which Analytics will show. Or I'm wrong?
