Let’s say you see a message on a web site which disturbs you some way or another, it annoys you, it offends you, you find it immoral, various other things.
You might think it’s a good idea to either take a picture of the screen (quite a non-technical solution), or just hit PrintScreen on a Windows PC and paste it in a Paint image/Microsoft Word document.
The thing is, it can be quite easy to change what you see on the screen, to manipulate the message.

What a web site like this is to visit the page for you and save it and put a time stamp. There are multiple solutions for this.
