It's described in this video. A child wore a cop costume and did bad ASMR. The YT description was "SASSY Police Officer / Cop Roleplay ️ SASSY AND RUDE" -- uncomfortable language when applied to a young teenager.
If I understand correctly, there was a young teen girl who did an ASMR video in a form-fitting “sexy cop” outfit. The whole thing was YT-monetized, and aided and abetted by her parents.
The even bigger deal was the fact that a YouTuber that made a video pointing out the problematic nature of those ASMR videos had his critical video taken down got a content strike.
