Is This Cheating To Improve Your Point Count?

Hi, I've been answering questions on Yahoo Answers only a week or two. I know there's no money or value to the "point" system, but I think I'm seeing a way to artificially boost my score anyway. Matter of fact, I used this system today to raise my accuracy rate from 10% (probably pretty good considering I only registered Oct. 28) to 14% - yes, in one day.

It's so easy, it seems like there much be some sort of "glitch" in the system here. Indeed, I'm afraid to tell you, for fear you'll cancel my account now, or my points, or something. It hasn't affected my sleep yet, but it might!

OK, this is Don's System for raising your points:

Apparently only some Askers really rate their answers, giving them 10 points if it's the best one. The rest go to voting. I'm noticing that many questions never seem to get voted on, and one vote alone is enough to "swing" the election. By going through my own questions that I've asked and going all the way to the beginning, I went through all of my 2 week old questions that were listed as "in voting", and gave all my answers a vote. You don't show people's icons or names there, but it's not hard to recognize my own answers. I like them anyway, I gave them all a vote. Apparently, that's all Yahoo's system is waiting for, because when I went to my email, here's everything I just voted for, giving me 10 points each.

Is this cheating anybody (except myself)? Why does Yahoo let me vote on my own questions, when they should know that as a typical too-smart-for-his-own-good human I'm going to be driven by my own greedy self interests here?

OK, I look forward to your responses. This is my very first question!
