I checked it. It was as reviewed. It seems to be a mechanism to acquire all the data that can be acquired regardless of whether it is necessary for displaying the website. This is a specification often found in general-purpose formats. This mechanism has the advantage that even beginners can easily launch a website but poses another risk to the net surfer local computer. They need to be familiar with such risks as they call themselves "digital support". I don't think they are familiar with it. The structure of their website speaks to their technical level. Even blogs published by non-professionals are far superior to this website.
