The Nintendo Switch does have parental controls, but it can't be accessed on the system itself. It's instead accessed through a smartphone app.



Also, what you're referring to is the yucks of Miiverse, which doesn't return on Nintendo Switch.



Basically, the Switch is what the Wii U should've been. It's got a few Nintendo ports, such as Mario Kart 8 Deluxe (An enhanced version of Mario Kart 8 with the Zelda & Animal Crossing DLC already installed, as well as King Boo, Bowser Jr., Dry Bones, the Splatoon Inklings, and a modified Battle Mode) and Pokken Tournament DX (Pokken Tournament with Empoleon, Darkrai, Croagunk, Scizor, & Decidueye.)
