They don't. Sometimes supervisors may accidentally do that, but they will always fix it later.
When supervisors combine questions into another question, that is called "merging." This is necessary when many questions are asking the same thing.
For example, the following questions are asking the same thing:
Why aren't the answers to my questions good?
How come the answers are sarcastic on WikiAnswers?
Why does WikiAnswers prove not good at getting you right answers?
These will all be merged into one primary question:
Why are there no good answers to my questions?
WikiAnswers is a website where a community of people answer questions. There are hundreds of volunteer supervisors and thousands of contributors that are involved.
Many contributors who want to be Supervisors are SPAs- Special Project Assistants. See 'related questions' for a full list of SPAs.
Questions on WikiAnswers can not be deleted by regular contributors. Supervisors can trash questions into a catchall category, but only advanced supervisors can permanently delete questions off the site.
The categories that are open only for supervisors are the catch-all categories. Note: 'Catch-all Questions' the category, not the catch-all categories (e.x. 'Adds No Value') is able to be viewed by regular contributors and regular contributors have the ability to add questions there.
Contributors and Supervisors change the wording of some questions to fit the Stylebook Guidelines. For further information on the Stylebook see the "Related Links" section of this answer.
Contributors cannot, but supervisors can. If you find a question that is inappropriate, unable to be answered, offensive, harmful, or illegal, then flag it or contact a supervisor.
Supervisors are a special group of users on WikiAnswers who have special powers on the website. Supervisor powers include the ability to merge questions, set question alternates as the primary wording for questions, and the power to block users who are making counterproductive edits to the wiki. Supervisors are users who have demonstrated that they are trustworthy editors and have contributed many helpful answers to WikiAnswers in the past.
The supervisors for the 'Questions about WikiAnswers' category are Kamuna and Dino10.
That's what it is in Wikianswers. There are thousands of contributors and these contributors answer questions posted by anyone.
WikiAnswers is moderated by Supervisors. WikiAnswers creators have decided to allow manual moderation, which makes the job a bit more complicated. Supervisors also rely on the Contributors to assist them by reporting questions or answers or Message Board comments that go against our Community's Rules.
WikiAnswers contributors, supervisors, and all the other 'special' groups strive to do their best in answering questions to the best of their ability. If you are still not satisfied with the answer, contact him or her and ask for a better explanation or of the sort.
You can only email supervisors if their email address is on their bio page. You can ask WikiAnswers your questions.
