Did you write a nice article and copy it to you? Have you made a nice website and copied images or text? Have you uploaded a video made by yourself and someone shares it without your permission?
Until a few years ago it was practically impossible to defend yourself online, mainly due to the fact that not all countries have the same laws, sometimes the damage did not justify the cost of an international case and so on.
And then there was little clarity about the location, ie does it count the public to which the website is directed, the language or the location of the server where the site is physically installed? There was a lot of confusion.
Today the situation is different. In Europe the laws are unified and finally clearer and more severe in this direction.
