The whole idea of chat board for kids is rather horrifying.
It's one thing to have a board where children can ask a question and that is answered by a member of nspcc staff, but to have a board where unhappy children can discuss with other unhappy children how to do things in secret. I presume there is no way for nspcc to know which users are actually unhappy children and which are adults with a multitude of reasons for wanting young children to do things to their bodies. And unhappy children are a damn sight easier to groom than happy ones.
Plus assuming it is all actual children, what the hell do they know about drugs and blockers and binders. Have they researched them, got proper data etc? No they've watched some tiktok videos!
From the looks of it the safeguarding from nspcc on this is non existent
