I agree it is a little clickbaity but it seemed like a good conversation starter.
Also - your friends articles are really good And I know what hithlain is, and you are right that someone over there is clearly flexing their nerd muscles
One the flip side, I have had to deal with the traditional horny player more than once. Sometimes they will go after NPCs and other times they will go after other players. The first is pretty easy to deal with by just casually indulging them. As long as it is not taking away time and enjoyment from other players I have no problem playing a short flirtatious scene, especially if it makes the player uncomfortable enough to not try it too often in the future.
Player on player action is more difficult to deal with as you really want the players to develop bonds within the party and it is good when they form naturally through interaction. Sadly, player on player can get uncomfortable for everyone involved, especially if it is really only one of the players who wants to go there.
I don't normally set restrictions for content at my table (unless we have children present) but I will sometimes step in and move the story along if someone appears to be appearing uncomfortable or the interaction is taking too long and does not really prove to be adding anything to the story other than fueling a players ego
I agree that the kind of thing in the article is thankfully rare, but then I generally only game with friends so I get to choose the kinds of people I play with. If I started playing with random people I meet online it might be a different story.
