Yes he does. Mingi particularly finds himself getting his ass tenderised by him. I'd even say Hongjoong is touched on his alphas than he is at his subs.

On whether he gets punished, it's more in the form of nips and being grounded. We see Seonghwa give Hongjoong a punishing nip in DD chapter 1 when Hongjoong gets too snappy and dismissive of him. He doesn't get smacked though, at least not by the pack he governs.....his seungmin and donghyuk hyung aren't above giving him a smack or two if he mouths of at his big age
