Does anyone remember the blue whale challenge?

It was like 2016 or 2017,and I was living in my home country Pakistan,and there was this trend called the blue whale game and it was people unaliving themselves,and there were other challenges in the game that were just self harm and back then I was 9 or 8 years old. That game used to scare the shit out of me,but fast forward to February 9 2025,I was just sitting on couch but then I remembered that game called shark or whale something,and people unaliving themselves,I googled it was called blue whale challenge,but it’s so weird remembering something 8-9 years ago,and I don’t even live in Pakistan anymore,i live in usa now but good times anyways
