Entirely depends on age and context. When I was a teen the group of friends I ran with would be constantly attempting to "hack" the other, so you were always on guard. Honestly I attribute that more than most things to my early interest in computer security and getting my foot in the door with programming. It turned into a pretty nice career so far. Sure it got tiring sometimes, but overall it was a great life experience I wouldn't trade for anything. We also kept this between ourselves. It's a much different situation if I "pwn" my friend who is attempting to do the same back to me vs. a typical normal kid. Those practices learned put myself and my friends in a pretty unique mental space for the time. It was an age in time where all this stuff was new, computers truly did not do as much important life stuff, and being a teenager playing pranks and cat and mouse was fun. Just this stupid "real world" experience in your mid/late teens was enough to typically get an entry level job in IT - typically starting off with more skills than your superiors. What was NOT OK were the few guys who never grew out of that BS. I ended a business partnership after I found out my "partner" had opened my workstation and removed the BIOS battery to reset things, and install a keylogger. At that point it's no longer funny, it was not a novel or interesting attack, and was simply being an untrustworthy asshole.
