Well, your junk would be deleted because we don't allow nudity.
However, if for some reason we did (or your junk was actually a ski photo) then yes absolutely you could get people to rate it up. We've been pretty careful about the system so it has some pretty solid 'gaming' protection built in... but I'm sure it will get gamed every once in a while.
When this happens, we'll change the system and protect it from happening again.
TBH though, what I really hope is that as a community we can take pride in the quality photographers amongst us. I mean everyone always complains that traditional media never gives enough exposure to the up-and-comers. We're taking that idea to the next level, and we want to give exposure to ONLY up-and-comers.
If we as a community respect our Athletes, Photographers and Video Producers - we will be the next wave of media creators.
So instead of gaming the system, go in there and rate photos, videos, news and anything else you can rate with your best and most fair mind possible. Then NS will have great content, and it will be made for us by us.
