Pinning on the stripes upon promotions. Do they still do this?

I picked up Cpl in the Marines back in 2014. It is more of a tradition thing, if the wrong people see it, people could definitely get in trouble... when I pinned I wanted to follow tradition, from the 24 hours of wearing the rank without the “turtles” on to walking through “the gauntlet” and endind with the wet down. It is like a way of passage

While we have gone to Velcro some awards still have pinned versions and some promotions can be done in limited company as to not violate hazing policies these days. I have pined some NCO's and drove master parachutists badges into chests (Upon request/with no video or photos taken) no to long ago. I am hoping one day to pin my fathers novice wings on my son, now thats gonna be fun as the pin is almost 1" long :)
To get back to your description of what used to happen, I know in the ARMY its a big NO NO and can result in others losing their rank for doing it. To me its a private thing now that its banned,I have my share of scars on my should blades and chest and wouldn't change a thing.

Cpl Vic Burk When the ‘hero’ in the movie Garden of Stone, (1988?), made SGT-5, he is depicted walking thru such a gauntlet. The 1SG punched him so hard he almost fell over. By the way - That was a Great movie w/o showing any combat re: Vietnam and the peacenik civilian culture of the era.
