Daddiesssss helpppp!! my dad has hit like on some adult stuff on facebook?

[Indian Kudi]

Im a 16 yrs old GIRL so i cant talk directly to my dad about this, me and my mamma had set up an account for her long back just for fun, she never operated it, i just logged on sometimes to check stuffs, my dad's other account is in her accounts friendlist not in mine so just had a look on his activities and i was so much ashamed, he has liked king of porn stuffs and its showing on people's news feeds, not when u check his timeline, but still its showing up over there, he has some of his professional contacts on Facebook and one of my cousin too, it will be so embarrassing if they see it, it's not my dad's fault and i know it, maybe he thought it wont show up or maybe he accidentally hit like on them, i tried to login his account with all the passwords he uses, just to delete those stuffs but didnt work maybe he has put up some other password which i dont know, what should i do about this? Please dont say anything bad about my father cuz he didnt do anything wrong

if you can't talk to him,don't worry about something which is out of your hand.
or
tell your dad casually like an information that when we hit like button on facebook other people get notification about it.
