No, spamming is unacceptable here on WikiAnswers. In fact, there is are group of people here called Supervisors, and their jobs is to get rid of spam on the site and block any person who violates the rules. Plus, some Supervisors become on the Vandal Patrol which is a gang of Supervisors, that look on various questions and message boards looking for spam and inappropriate language. If you like spamming sites, let me tell you, that WikiAnswers is not a good place to do it. If everyone were to create an effort, this site would be the most helpful question and reference topic site on the web.
Obviously terrible answers (such as "your mom", "bye", "QCHICKEN5", and others), spamming, vandalism, and virtually anything that does not conform to our Terms of Use and other rules.
No, you cannot have the letter Ä in a username on WikiAnswers. You will get the error message: "Invalid Username: Only letters, numbers and underscores are allowed!"
