Parental controls

PieClips is for adults only. Every page carries the RTA (Restricted To Adults) label, which most parental-control tools read automatically, so they block this site without any setup beyond switching them on.

Android: the Google Family Link app.
Windows and Xbox: Microsoft Family Safety.
