Context: In a video of Recep İvedik's music, there was a comment which said "lymph cancer 4. phase know the value of your life" A lot of people wanted his phone number and his Instagram to be a friend for him. He deleted his videos and left a message saying "vids are deleted" in his bio. One day, Cem (not quite but his gf) said: "Seyyit Cem Karabiber died this day." Everyone was scared and sad because of that. If you go to his channel and click his only video: you see everyone saying stuff about his death. If you want to see the video (it's in Turkish, but you can activate transtlate) copy this link: https://youtu.be/7ak2W12pmvg?si=UKo24UWClzfiBCl3
Hope this helps :)
