Tasha while Iām not familiar with your custom, unless belting children is an acceptable, or at least tolerated, secrecy is understandable.
The risk of being sued for child abuse, losing reputations, or just creating a scandal is very high.
Also a chastity belt is a sextoy, and there are countries where using a sex toy on minor is a crime per se
There is not a single case in this forum in which belting is public.
