Charities and public services must not share kids or encourage kids to share their troubles with social media and ad systems.
Social media only allow sites to use their embeds if sites respect terms regarding age limits, parental consent and data collection.

A complaint of a similar nature to the NSPCC concern has been registered with The Children's Trust
The complaint was raised recently. I am currently awaiting a more complete response before determining what is appropriate to share.
