Haven't heard of any other platforms that use cartoons in the UI, actively associate with kids hobbies, and also make it one click to join active pedo grooming communities.
"very good moderation" makes me believe you work for them because that is a laughable notion.
I would bet that Big Balls swatting/SIM swapping/ddos community "the comm" still has dozens of discords that have been up for years
Any social app with one click to join communities (all of them) will fall under this.
And how out of touch with teenagers are you that you think cartoons in the UI (whatever that means) are why they use it. What is a kids hobby? Gaming? You cannot call that a kids hobby.
Any platform that’s popular will have its share of undesirable users, out of the company’s control.
Discord has very good moderation in contrast to other platforms (Constant banwaves on illegal/shady servers, terminating accounts frequently, etc)
