EDC China took place over the weekend in Guangdong with a totally stacked lineup. What everyone is buzzing about, though, is a warning that organizers allegedly passed out in the green rooms.

“BEWARE,” the notice reads. “No swearing or bad language on the microphone during your performance today, or you risk being detained by the local police. You have been warned!”

If this is true, which it looks to be (see below), then artists including Zedd, Dimitri Vegas & Like Mike, Infected Mushroom, Joyryde, Kayzo, Lost Frequencies, 12th Planet, Kill the Noise, Tiƫsto, Steve Angello and more all ran the risk of being arrested. That is, if they used naughty language on the mic.

Let’s be real — it’s not uncommon for an EDM track to drop an F-bomb, let alone a DJ taking to the mic to express their sheer excitement. If Alison Wonderland were on the lineup, for example, we all know she starts up almost every set with a welcoming, “What the fuck is up?!”

It seems everyone was on their best behavior during EDC Guangdong, because we haven’t heard of any incidents to come of this. Do you think it’s OK for festivals to put the crack down on swearing? Read more on the discussion here via Reddit.
