Okay. Without knowing the sites in question, I will try and explain a bit of what is going on and I will provide just a few links.
I get the following domain names associated with the new method of referrer spam that people are seeing of late.
The difference is that, in theory, rel="noreferrer" should not have any SEO impact, while nofollow clearly specifies that the link does not endorse in any way the target URL.
nofollow was invented by Google back in 2005 in order to fight comment spam in blogs, any URL appearing in the comment section would not pass PR to the target webpage.
This is not valid traffic, it is called Referrer Spam, this kind of spam uses a Google Analytics weakness to make fake visits to your site, so they actually never visit your site.
This Ghost Referrer Spam targets random GA tracking ID's with the only purpose of getting traffic from people that get curious about the referral in their analytics and try to go ...
Unfortunately, you can't. Google search now exclusively uses HTTPS and all search result clicks go through an intermediate URL that removes the keywords. The URL you posted above appears to be that intermediate URL, and that's all you get as the referrer.
The reasoning behind this is that each user of Google often gets personalised results based on their ...
As John says, this is fake traffic known as "referral spam". This morning I had about 80% of my "traffic" coming from this same domain.
Rest assured, you are not paying Google for these clicks.
The basic idea behind referral spam is that some hosts will publish their logs or Analytics data publicly, thus creating links and/or text references to their spam-...
I can confirm that Google Analytics will start a new session when the user comes back from logging in with the referrer from another site. I don't have as big a problem with it on my sites because not many of my users log in. From Google's referral exclusion documentation:
How excluding referral traffic affects your data
By default, a referral ...
That means that the visitor did not send a referrer for the request. That can happen if:
The user was a "direct" visitor and typed the URL into the browser bar or used a bookmark.
The user followed a link from outside the browser (for example from an email or mobile app.)
The user came to your non-secure http site from a secure https site and the browser ...
The Spam is getting out of control. The list it's growing and it's time-consuming and not even efficient to add a filter for each of the spammers since most of them shows up for a few days and then disappear and a new one comes.
There is a lot of misinformation, the most common mistake is recommending to use the .htaccess, this file blocks the access to the ...
I assume you're referencing Blogger (blogger.com)?
Referer spam has been a problem on Blogger and other blogging sites for a very long time. Unfortunately there isn't an effective way to block it because it's very difficult to distinguish legitimate referers from spammers.
Editing your robots.txt file will not help because spammers often use fake user-...
There are plenty of threads about this in the Google product forums:
Lots of visits through simple-share-buttons.com
How can this be self-referrals if the domain is nothing to do with me
How to block 4webmasters.org, Russia traffic?
What is Google doing about all the SPAM in Analytics?
Here are some of the best comments from those threads:
You can exclude them by creating a filter. You need to find something specific enough so you don't accidentally block good visitors and it is tedious as you have to manually add each spammer but this will do the trick.
This is just referer spam, from Wikipedia:
Referrer spam (also known as log spam or referrer bombing) is a kind of spamdexing (spamming aimed at search engines). The technique involves making repeated web site requests using a fake referer URL to the site the spammer wishes to advertise. Sites that publish their access logs, including referer statistics, ...
In most cases the URLs used in Google Search Results come from their search index, and therefore will be based on the canonical entries they have. e.g. it will be the https version of your website redirects all http pages to the https.
However, you define which URL is used in your Google My Business entry, and that is the one shown for the website link when ...
To answer your title question directly "How to fight off referrer spammers" the simplest answer is to drop Google Analytics and switch to Piwik, which automatically blocks all referrer spam by default.
I realise you are probably used to Google Analytics and wish to keep using it, but if you look at the bigger picture you do have another option which works ...
I would check your log files to see if this is referrer traffic to your site as opposed to Google Analytics. There is a new spam technique seen here: How to fight off Google Analytics referrer spammers? though neither of these domains are owned by this spammer and this answer may not apply- it is well worth a read for general knowledge of a new technique.
It's just spam :) Scripts can send Pageview and Event data to random GA tracking codes without visiting your site. The best fix is to create a filter that only allows requests originating from your hostname(s). This is a great article on it:
<a href="https://validator.w3.org" id="allowReferrer">Link that you do want to ...
The idea would be to make your requests look as much like a real browser as possible. Real browsers send referrer headers. You'd want to send referrer headers that look as much as possible like the referrer headers that a real browser sends.
A real browser never sends random referrer headers. It sends a referrer header for the previous page. Most ...
It sounds like you are on dangerous grounds.
I assume that Googlebot will always get the same page since, according to your example, there is no search involved. But please do know that Google checks pages using domain names, IP addresses and agents other than Google's own to validate that a page is not cloaked.
What you are describing falls within the ...
The only way that Google knows your page is about bears is that you give it content about bears when it crawls the page. When Google crawls the page, you have to choose whether it is about bears or lions. Then Google ranks the page for the appropriate term. When Googlebot crawls, it doesn't send a referrer, so you can't make the decisions based on the ...
I've got the same from lots of spam referral doamins and I want to share a PHP code that you may include in your header.php or something else.
With this code you can redirect the spam domain to itself.

Google Analytics now has a Referral Exclusion List. Select your property, go to Admin, then Tracking Info, then Referral Exclusion List. I just started using this feature to block 4webmasters and some other particularly annoying referral spammers, and it does appear to be working.
"nofollow" is used by Google, to specify that the Google search spider should not follow that link
Specifies that the browser should not send a HTTP referrer header if the user follows the hyperlink
Take a look at https://www.searchviu.com/en/spam-traffic-google-analytics/. This is a good article on setting up GTM with additional parameters so that the only hits that show up in Analytics are genuine hits.
The process basically identifies "all hits that you control and exclude all other hits, that do not carry this identification" by adding an ...
Is it possible to check on the end (3) that user visit came from (1) my shortened link?
No, because "(1) my shortened link" is not the referrer. The web page that contains "(1) my shortened link" is the referrer and it's this that is potentially*1 passed down the line by the browser.
Webpage-X contains "my-shortener-...
