In many cases, the next step is to review who can message, follow, add, tag, or invite your child.

You can focus on the controls most likely to help, such as message filters, private account settings, friend approvals, and restricted contact options.
Some situations need more than blocking, especially if your child may be responding to unknown users or feels unsure about what to do next.
Start by blocking the specific account, then review the app’s message settings to limit who can send direct messages, chat requests, or invites. On many platforms, you can restrict messages to approved contacts or friends only.
This usually means blocking alone is not enough. Check whether your child’s account is public, whether anyone can send friend requests or message requests, and whether the app allows discovery by phone number, username, or mutual connections. Reporting repeat accounts may also help.
