Based on the results of Internet monitoring (manual queries in search engines, plagiarism checks), you can establish that someone has borrowed your materials. If you see that the content has been copied, try to talk to the owner of another site. If the result of the negotiations does not satisfy you? File a claim in a legal manner.
It is necessary to have a clear rcs phone number data understanding of the properties of information on the Internet:
Data is distributed online in the shortest possible time. Because of this, it can be technically difficult to prove that your site is the original source.

The vast majority of materials on the Internet are not copyrighted. They are various combinations of them. Here, copyright law will be useless.
The legal side concerning the Internet is poorly developed, and therefore additional litigation can only aggravate, rather than resolve the problem, especially in your favor.
Search engines, being giants of the IT industry, use a lot of legal loopholes. It is quite possible that those who parse your data from the site will use them too.

Psychological measures
Here, everything depends on your mood and how appropriate you consider this or that approach. If you want to act tough, use technical or legal measures to show that it is easier for parsers to find another resource than to fight you.
