Go into stalker portal, go to "settings, then go to " parental control " (I think that's what its called), and change the password to a new one. Your IPTV service would have provided you the default adult pin/password when you signed up. It is ususlly either '0000' or '1234' or '0123'. Then reboot the box. From now on, it will ask you for the PIN/password whenever you try to access adult content.
You could also ask your IPTV service/reseller to remove you from the "adult group". Most IPTV services can do thst for you. That way, the adult channels aren't even visible or watchable - they don't exist on your end
