Evidence and facts
Separate observations, reports, and inferences.
“I paid” and “They intended to deceive me” are different claims. The first may be supported by a payment record; the second makes an inference about intention. You can record a suspicion while identifying what supports it and what remains unknown.
A screenshot is not self-explanatory. Its source, completeness, and connection to the event matter. A payment image alone may not show what the payment was for. Whether material is admissible in a particular proceeding depends on local rules.
Keep original files and context, and prepare a separate chronological account. Do not alter originals to make the story cleaner. Use fictional material for this exercise, avoid exposing personal information, and never access someone else’s account to gather material.

Separate checkable statements and inference in: “He ignored me after payment, so he is a fraud.”

Checkable: payment time and amount, agreed terms, message dates, and replies. Inference: the person’s intention. Missing: whether delivery was due, alternative explanations, and whether messages were received.
