Parental control, how to block all adult channels

[mankind]

I have a IPTV subscription that contains many adult channels. I tried to block them by using Parental control, type the name of the channel
and then add it to the list ( it appears with open lock ) , then i put the password and save. But the channels not blocked !!

also another question, How can I block all the adult channels ? should I write them manually one by one !! they are over 70 channels

Is there a way that i can select all of them ? or select a group of channels to block ?

It will be easier to buy an individual TV for children.
