Mods

Why can mods put up adfly links and we as non moderators can not? i got a link taken down because it was an adfly link, but while searching for a texture pack, i found that moderators can use adfly to like their downloads... WTF Why can they do that but not us? I really would like a response about this problem. if you know tell me... seriously dont get mad cause im rating about the mods or anything im just wondering why they are so much better than us and can do that...
