Okay, I see people, and how they cover their mac addresses, but what can they really do? I mean, does a mac address only tell an internet connection a device with that number is logged on? Like an Internet Protocal? I mean, how can a "hacker" hack a mac address? It seems pretty stupid to me, and quite childish for a person to hack something like that, but Earth houses a lot of lowlifes, so really, **** like this will always happen. Well, I hope someone can tell me what this is, than say, "OMG ARE U FEEAKIN STUPED? I MEAN, WTF R U RETURDED?"
