TikTok complaint: Bullying

My daughters account has recently been permanently banned by tik tok with no explanation. My daughter is being bullied at school and one of the things they used to do to her was take the mick out of her tik tok dance videos and she was worried about deleting them of her friends as she feared they would bully her more. They told her recently that they would get her banned and that appears to have happened. She noticed last night her account was banned and when she got to school this morning they told her that she was off tik tok. When she asked how they knew they replied they got her banned by keep complaining about her videos. They have been laughing at her all day over it and she is completely heart broken. As a mother is extremely upsetting. I wasn’t completely happy about her wanting tik tok but I saw the joy it brought her when she did the dance videos especially Jason Derulo. She feels she has don’t something wrong and because of the bullying the is feeing like this a lot. I won’t to reassure her that she hasn’t done anything wrong but how can I do that in this instance when we don’t know why she has been banned and why permanently. I monitored her videos and can’t see why she would be banned. Can you please elaborate on this.
