As someone who has spent time in the Corporate and Academic worlds, the random Hugs, Kisses, and Moons, (not to mention Splankings,) still cause a bit of trepidation for me.
I can see where this could be used to annoy someone or make them feel uncomfortable. I admit that while I constantly play music blocks for others, or randomly donate small items of food or drink to others, I don't in general do any of that stuff past the required amount for the quests.
It makes me somewhat uncomfortable tbh to even have those options in the menu, but I applaud those who have a freer attitude than do I.
