It's just waaaaaaay too obvious for Artemis to be the mole. It'd be an anti-climax if she was the mole, 'cause we've known it all season, since she was introduced almost. It's just something for the younger viewers to say "I KNOW WHO IT IS!" and keep them watching, while the older viewers think "hmm, I wonder what they'll do with her?" which keeps them watching.
