I did not mean to imply that JohnSnow has not encountered a bug. Or that he needed to prove it. This same issue has been reported by players in the past.
My point was: Many players state that they “have screenshots”, but don’t post them. So, why even say you have them if you’re not going to include them?
This is from the sticky, How to Write a Good Bug Report:
Finally, it always helps to attach a link to Imgur (or another picture hosting site) that displays a screenshot of the bug. If you need to include a video, link to a video as well.
