Authentication – How does Ranker.com recognize wrong voices without registration?

I've reviewed the Ranker.com website, and their voting system can not be fooled by fundamental changes in our public information. So I checked how the voting system captures votes without the user being logged in.
I've upvoted / downvoted a post and then made the following changes for each test before opening the same link in a new window to see if the voting system is actually being recorded in a browser info or via an IP address or something else.

  1. Just change the window, the vote is still available.
  2. My IP address changed, the vote still exists.
  3. Opens an incognito window, the vote is still available.
  4. Opens an incognito window and changes the IP address before the link opens. The vote is still available.
  5. Modified the IP address, voted on the post, opened an incognito window and changed the IP address again, the vote is still there.

By now I thought it might be in the browser. Maybe they inject something into the browser to confirm the change, but then it should not work properly in the incognito window?

To check for the possibility that browser information may be saved for clicking on upvote or downvote, and checked before each reload, or for every link opened in another window, before we can vote or retune, it made sense Needs time for a newly opened link that reflects our vote.
I also checked which request parameters are sent when I click on an up or down vote while I do this in the normal window and then in an incognito window. (As I can see, the votes are never changed). The Inquiry Sent parameters recorded when you press Up / Downvotes are as follows:

{ "User votes"[{"nodeId":73337736,"type":"UP"}]}
{ "User votes"[{"nodeId":73337736,"type":"DOWN"}]}

So I could not find how to record the change and link it to the browser. ("I think I've overlooked some browser information sent here because many clicks were made during a click, but I could only find these parameters in one file, please help me if I've missed something here.")
So the parameters had no browser information (according to my analysis)

The only way was to check it with two different browsers instead of two different windows on the same tab.
And surprisingly, the system did not work to detect a wrong vote on the same IP, just another browser. So I think that while recording the voices, something definitely has to be stored in the browser.

Could you please tell me how the voting system works? These were my attempts to guess, but I could not find anything other than the fact that other browsers could bypass the voting system.
Please also put a light on "Is the browser info saved?" (If so, then there is something other than IP that web sites can record, unless they put something in the cache, but that should not work in incognito mode.)).
Any other method or related reference would be very helpful.
