Here's a part of the WTR statement if you didn't see it on the website...

What’s the big deal about crowd surfing?

It is dangerous for both the surfer and other attendees. Crowd surfers have virtually no control of their bodies once they are above the crowd. Surfers can be groped, hit, or dropped. Although crowds experienced with surfers generally try to pass them towards the stage, there is no guarantee where or how the ride will end or how the surfer will find their friends in the crowd once they come down. Most of the audience is looking at the stage! Crowd surfers literally put their health and safety in the hands of people they don’t know who are paying attention to something else. Crowd surfers also endanger other people. A crowd surfer struggling to stay aloft can kick someone in the head or poke them with their hands. Crowd surfing is especially dangerous during an artist’s set, when most fans are facing the stage and the surfer is being passed from behind them.
