知識長燉冬菇

假設沒有管理員移除問題干預下, 仲有其他 scenario:

Scenario 1: 知識長唔再答問題, 即係唔會再被選為最佳答案 or not, 唔會影響到採用率.
咁呢個知識長嘅降級就取決於佢嘅最佳解答比人負評(惡意與否則不加評論), 導致扣分. 佢一日有2501分或以上嘅, 因為取決於採用率 (唔變) 同回答數 (唔變), 都仲係知識長. 但當扣分到2500分以下, 就會變成小學級. 1, 2, 3, 4, 5咁落, 到0分以下就變成幼兒級. (詳情請參考知識等級表)

Scenario 2: 知識長繼續答問題, 但因為任何原因唔被選為最佳解答, 影響到採用率.
當一個知識長答咗2000條題目, 有1400條被選為最佳解答, 採用率 70%. 佢下一條問題(第2001條)冇被採用, 咁採用率 = 1400/2001 = 69.965% = <70%, 會變成博士級1級. 基於2501點以上嘅級數係以回答數及採用率將作為以後升級標準, 而回答數已經肯定超過125條, 所以就算之後呢個知識長答任何問題都唔被選中, 採用率一路下降, 都唔會跌低過中學級.
極端情況下, 被選為最佳解答停留喺1400條, 當佢答到2334題時, 就會跌落碩士級1級; 3501題時就跌落大學級1級; 4667題時就跌落中學級1級. 回答數已經唔會影響到每大級中間嘅1,2,3,4,5分級.

好像聽說有人被檢舉被刪數百題。

恕我無甚觸覺，是否真的有管理員移除問題干預下重大變級的情形呢？
制度有規則，管理員移除問題則似乎無劃一標準，移除原因往往籠统，有需要監管這種行為。

知識長 can be Demoted to:

博士級, 碩士級, 大學級, 中學級 based on 採用率. (In this case, all newly demoted rankings will be remain as 1 級 as the sub-rating because 知識長 has to have 2000 回答數 to qualified.)

知識長 can't be Demoted to:



小學級, 幼兒級 based on 分數範圍 (知識長 has a large pool of points. Unless 知識長 wants to sabotage the rating, it will be so difficult to reduce 知識長's point to less than 2500 points).

Yes. All demoted will be level 1 regardless because the level is based on how many questions you have answered and that number is not going to drop.

Same as 博士級, 碩士級, 大學級.

2010-02-18 16:23:45 補充：
As I said, all demoted will be remain as Level 1 because of the questions that they have answered. They are demoted because of the 採用率.

Also, 知識長 has a large pool of points. Unless 知識長 wants to sabotage the rating, it will be so difficult to reduce 知識長's point to less than 2500 points

Then you need to ask Yahoo!. The reason - those situations rarely come separately.
