||Or it could just be jin.
Of course, jin fits into one of those categories, but I can't remember which one.
My personal theory is that this alleged 'luisa' person is actually an infiltrating member of a government society looking for weaknesses wherein they can stomp out this final bastion of controversy on the internet. Normally, it would be rather rash to draw conclusions about a random new person of unknown characteristic, but this person rated up legolas. Surely anyone but the most obviously inept of government spies would know better than to do such a thing. After all, it's legolas. What's he going to say that's worthy of a four? Nonetheless, I wouldn't worry too much about this 'luisa' character. I don't think 'she' poses a threat. Like I said, she's pretty inept as government spies go. Why, even the worst of my old coworkers in the illuminati would be able to find out everything they need about a web site without drawing near the attention this 'luisa' person has. Let's just lay low, and not tell her about the information smuggling operation, or the underground accumulation of rat-strength painkillers.
