Your videos have been flagged due to incorrect tagging. The videos are about "The Wizard" while it has tagged " Arizona Sunshine, Horizon Zero Dawn, Intruders: Hide and Seek" and "Gang beasts" while it is tagged as " Days Gone, Job Simulator, Paranormal Activity: The Lost Soul, Racket Fury: Table Tennis VR".
You always have to make sure you are putting the exact tags from keymailer into the video (best is copy and paste, as even 1 space in there can make keymailer not find it). If you tag multiple games, and your account gets checked it will get flagged. A flagged video does not count towards the accreditation anymore, so even if you have 3 videos on your content stream and one of them is a flagged one it will only count as 2 videos.
