Yes. it sends some random data from that player to some random investigation team there in jagex place and they see from the random data if there is automate code dropped in the data, and if there is, BANHAMMER FTW Hmm... Here's a metafora: Person1 sends an apple to leet grandma. (which is report of some player, non autoer), grandma is so leet that she knows if there is poison in there (aka macro script). IN this case there is not, so she can make an apple pie off it and eat it. But if person1 sends an apple, poisoned apple, grandma can smell it, and know it's bad, and throw it away (aka ban the macroer). And i know that doesn't make sense at all, and i dont know why i wrote it, but anyways *shrug*
