How does it affect the fact that my content was stolen and placed on another resource?

Question

Search Engine Optimization

Good afternoon!
I have a question, recently my content was stolen from the main page and placed on a third-party resource. I scored the content itself in Yandex Webmaster in Original texts. Will the presence of my stolen content located on another site affect the position of my site in Yandex and Google. Copied exactly the same, without changing anything.
Wherever I look they write, if the content is clogged in the Original texts and indexed, then it is considered unique, and other copied ones are plagiarism. And accordingly, it seems that positions should not be affected. But I want to know the opinion of experts!
The content of my site has been indexed for a long time! And according to the words, he was in the top. When someone else's content was loaded, I can not yet find out. But I think later, since my site has been in the top ten for a long time. Now he's out of there!
Thanks for the answer!

Answer 1

If you don't see someone else's site, don't worry.
You can fall out of the top for a variety of reasons.
By the way, now it is possible to present legal claims and simply block the competitor's domain.
