What service / site can be used as an "honest" website screenshot?

Question

Computer networks

For example, there is a question on the toaster. I'll write a comment and then delete it. How to take a picture of a page so that when it is presented to another person, he agrees with its authenticity (a regular screenshot can be faked, starting from the source code and up to Photoshop).
I hope the question is clear, thanks in advance for the answer!

Answer 1

Here: https://www.proof.com/screenshot/ The service is not free (30 cents per screen), but the screen will have full legal force as proof.
