How Easy Is It To Identify A Fake Screenshot (really)?

This thread was inspired by another thread where I saw a mod talking about how they will delete a thread and ban a seller if they use fake screenshots.

I am not trying to get banned by posting this thread. I've always been extremely curious about this topic and rather than hijack that thread, I figured I'd make a separate thread. I'm going to make some bold claims at the end of this, and would appreciate some honest answers.

As someone who's been using photoshop and for 8 years, and can do virtually anything with the program, I'm curious how the pros or experienced moderators identify fake screenshots?

The way I've always seen it, if someone has the slightest clue what they're doing, there is no way you can tell a screenshot is fake. Counterfeiting money is a totally different story, since you're up against the secret service and are dealing with a tangible commodity. But a screenshot? A screenshot is nothing but a mere image. Most of the time, a very basic image. Its mostly just numbers, squares, shapes and colors.

In photoshop you can magnify images by 1600% and literally compare 1 pixel to another. So if something is off, a font, a shade or color, if 1 pixel is off, its easy to see and fix.

In web design, many times I've copied designs or certain graphics from other sites. Then I change some colors around, change some fonts / colors etc code it to html and use it for my own sites. Most of the time I "remix" the graphics. If its something small like arrows, I usually just steal them and don't make any edits (I have an obsession with arrows ).

I also know from copying and pasting my own Clickbank screenshots (I have a journey on another forum going). To post my screenshots, I have to copy and paste them into photoshop. Then I usually magnify the images and censor the last 2 digits of my sales, so people can't trace what products I'm selling. But you can see, clear as day under magnification, that a child could reproduce a fake screenshot within minutes. It would take seconds to change the numbers and I see no way in the world how someone could tell its a fake. I also remember seeing a video on YT where people do it using some type of java code. So the screen itself changes right on Clickbank.

I'm not trying to start a controversial thread. I've just never seen someone make a thread like this and ask such bold, direct questions.

These are my claims / questions:

1) Isn't it true, that the high majority of screenshots can easily be faked? (if a person really wanted to?)

2) And isn't it true, that most of the time, noone (including noobs, vets or mods) can tell? (I said most of the time, not all the time )

Keep in mind, I am NO expert on this topic. And I only have 1 CPA account and a Clickbank account. Maybe other networks have signature trademarks they use that are harder to copy. But I've seen so many screenshots from many different networks (that other marketers use), and most of them are just numbers, tables and squares.
