Some answers are incorrect and some are nonsense in those cases the answers are either edited or removed. This is done in order to make sure that no one is misinformed or in some cases offended. Also, some contributions to the answer page are debates and some are discussions that do not directly answer the question. Often a new contributor doesn't take the time to read the guidelines available at the Help Center and starts off on the wrong foot.

Not all answers on WikiAnswers are useless. Usually unhelpful answers are posted by WikiAnswers users who don't know what they are doing, and post answers to questions even if they don't really know the answer. If you find an answer on WikiAnswers that is unhelpful, you can remove it or flag it for improvement using the tools on the blue bar on your left.
The two main reasons for contributors to delete an answer on WikiAnswers and save it are to remove "bad" answers or to vandalize.
As a website, Wikianswers does not have such a position. However individual contributors may often remove answers that they believe to be from the 'wrong' viewpoint. If you get into an edit war over different, but valid answers, you should contact a supervisor to mediate the issue.
Some people on WikiAnswers do not understand the concept of a Wiki, and end up replacing answers with their own or adding their answer after an existing answer. Answers on WikiAnswers are meant to be answered with a single, unified answer. Users should not remove an answer to replace it with their own unless the existing answer is entirely incorrect.
To delete an answer, you go to the question, click edit, remove the answer and click save
While the majority of answers on WikiAnswers are accurate, there are some answers posted that are not, as well as answers that have been vandalized. But there are Supervisors who are constantly patrolling the site, as well as many knowledgeable contributors who continually add valuable, correct information and remove the incorrect and vandalized answers.
All complaints should be sent to: WikiAnswers @Answers .com (remove spaces)
Sadly, there is no way of stopping incorrect answers from being added to the site. The only thing we can do is remove them and work on another, correct answer.
WikiAnswers removes signature lines from answers because answers do not belong to one specific person. If you answer a question, odds are it will be edited someday. We all edit answers to update them, add more information, or clean up the format of the answer. If a user puts their username (signature) under their answer, they are claiming the answer. All answers are a community effort.
You can. There has been no changes to stop answers.
Anyone can answer a question in WikiAnswers (that's why it's a 'wiki'). As for people who post rude or insulting answers, we try to find these and remove them. You can help the supervisors by flagging answers that were obviously written to offend.
