This isn't so much a discussion of the series but I have noticed it has gone from being number 3 a few weeks back to number 9 now, I wouldn't think much of this but the weird thing is that 185 people have rated worst ever while only small numbers rated it at awful, bad, weak, not really good, so so and decent, in fact the only very good, excellent and masterpiece received higher votes, doesn't this sound like voting to change something's position in the ratings rather than give your real opinion, which I was under the impression was against the rules...

It's called rating spamming and we are aware of it. Similar issues have been discovered over two years ago.
Unfortunately, with the exception of evident ones e.g. creating multiple accounts to rate, it is virtually impossible to stop people from voting "worst ever" to some of the most popular series, for every user has the right to rate however the score with whatever reason. Checking and comparing the IP addresses of those 185 users would be time-consuming and ridiculous. There is an algorithm to minimize the effect of spamming (and because of it you see the same number of votes does not necessary mean the same length of rainbow bars), but I don't know how it works (only Dan knows), and I wouldn't tell anyone even if I do know. |

I don't want to sound to mean but I think you should do anything that you can to make sure votes aren't being tampered with. If this means checking IP addresses go right ahead. Sure some people could use IP jumping programs but at lease it's a try. |

Ah so those bars represent how it's actually valued eh? It's not so bad then as the bars are not that long, also the same thing is happening with death note too

Sometimes it's easy to catch voting tampering because of the method by which ballot box stuffing is done. Sometimes it's not so easy. And sometimes it's actually genuine voting. Who are we to say "The guy over there who likes Starblazers and hates Haruhi is voting the wrong way"? |

A few things worth noting:
1) It's common for very hyped titles to fall in the rank after a while. 2) Many people tend to vote towards the extreme, voting "best ever" and "worst ever" exclusively. This is why, for many titles, "worst ever" is longer than "awful." People who regularly vote at the extremes have very little significance in the ranking, so accounts that are created for the purposes of ballot stuffing don't really affect much. 3) Some of the people who voted "worst ever" for dub voted much higher for the subbed version. Only their higher vote counts towards the ranking. 4) Yes there is some ballot stuffing going on, but keep in mind there is probably positive ballot stuffing going on for Haruhi as well, also negative, and positive ballot stuffing for the titles above and below Haruhi on the ranking. What little effect it may have more or less cancels out. 5) Haruhi was just released on DVD, so it's to be expected that the # of votes would increase significantly in recent weeks. 6) Compared to some of the titles above Haruhi on the ranking, the number of people who voted "good" and "decent" has done more to bring Haruhi down in the ranking than the people who voted "Worst ever." Many of these people are the people referred to in #5, and they clearly aren't ballot stuffer, otherwise they would have voted one of the extremes. All these issues combined make me feel very comfortable with the conclusion that there is nothing wrong with the ranking system. Certainly people try to abuse it, but they fail to have any effect. I'd also like to add that any type of automated IP based ballot monitoring would do more harm than good. 500 people behind a proxy server or NAT, all voting legitimately, could have the same IP address. Some proxy servers forward the client IP, however NAT does no such thing. -t |

Pseudo-SQL: change to fit your DB schema
That'd be a pretty fast way to check, if you know someone with direct access to the db. |

Thanks, but we're aware of the required sql code, but it's not feasible for us to manually check 6000+ titles, nor is there any point. Although this issue was brought up for Haruhi, it's actually an issue for many titles. But as I explained above, it's more of a non-issue than actually issue. The system is such that the vote spam has a completely negligible effect. I'd be willing to bet that if all the spam was removed from the ency, Haruhi's rank wouldn't change. -t |

I think you're right tempest, it probably is the recent dvd release and all... Anyway While we're on the topic one thing that would be easy to watch for are accounts with few votes and only votes at the extremes

As previously stated, the system does "watch" those people. Their votes are worth less. -t |

Honestly, Youre best off to just ignore these Ratings. Even without people manipulating the ratings its not going be all that close to accurate.
If you want to know how good something is, just go read a review. Theres tons of em out there. They'll be so much more ballanced than your average "OMG it was teh best/worst Anime ever!!!!" fan reaction. |

Indeed, why bother if Haruhi is ranked 1st, 10th or 50th ? Open the details in the user rating section, and you'll see that all ratings (median, arithmetic mean, weighted mean and bayesian estimate) state 'Excellent'. The rest is of minor importance. |
