This thread is pointless. Although there are plenty of threads with swears and talk of drugs and sex and whatnot, there's really no good way to sensor it. If you make an age limit they'll just lie about their birthdays like I do for porn. Yeah, there are little kids that post dumb stuff and shouldn't be reading the threads or whatever, but maybe their parents should handle what they do on the internet, because age limits don't do anything.
I personally am stoked on seeing younger and younger kids throwing down better and better tricks. There are probably a good deal of 9 year old that stomp sicker tricks than some 18 year olds on NS. Some of the youngest kids are some of the reasons that the freskiing community is constantly growing, earning more and more respect, and progressing every day.
So I say no... We should be encouraging the younger kids to get in the park. I fucking hate when gapers ruin the sides of jumps, but if the kids are actually involved and interested, It's a good thing that the freskiing community has the younger members.
