This one comes by way of Idolator.
The BBC reports that rule-making types at the Reading and Leeds Festivals in ye olde UK are cracking down on the jolly act of rolling 'round atop the hands and faces of your fellow concert-goers in order to show that you are having an awesome time.
At most concerts, fans are simply put back into the crowd when they reach the security pit below the stage.
But at Reading, they will be ejected from the arena and forced to walk back to the main entrance to get back into the site.
"Reading Borough Council Health & Safety team consider it quite dangerous and we will endeavour to try and limit the amount of times people will do it," Mr Benn said.
"They won't be ejected from the festival but they'll be ejected from the arena. What that will result in is probably around a 20-minute delay before they get back into the arena. It will certainly delay their ability to get back in to watch the band."
Will it stop people from crotch-gliding on other people's foreheads? I don't know. On the one hand (so to speak), the crowds might just try, collectively, to keep from moving people within reach of security. On the other hand, crowds don't always work real well together. I've never been a huge fan of crowd-surfing, myself. I prefer to stand still with my arms folded and a dog-eared copy of L'Etranger in my back pocket. But it's a rite of passage, I guess, and I doubt people will stop doing it any time soon, even if it means getting kicked out of the show, since people who go up aren't always paying so much attention to the band in the first place.
