I always considered image searching as cheating too, but some people have... a more relaxed point of view on that subject, and it's not really written anywhere.
So, unless players agree on a new set of rules the only ones are "I will give you a screenshot
of a game, and you will answer. If an answer is true you can ask your question. But point is the person who is asking the question must verify the answer."
But a screenshot is just that - a screenshot. It's not a cropped picture, or a picture with parts of it blacked out. It's a screenshot. And I've found that most of the entries here are not screenshots.
