Autumn requested to have them deleted (i'm pretty sure)
I can't find the exact post - but she posted hashtags like #myaccwillbedeletedsoonmissyall and #momdeletesaccount. Her mom probably found out that she had a KT and KS account and made her delete it.
Here's some links to some of the posts she made (you can see the hashtags) https://www.kidzsearch.com/questions/64168/whats-your-rank, https://www.kidzsearch.com/questions/64166/bangladesh-shuts-all-educational-institutions
