Why do my Answers always disappear on this site?

I never get a violation, bcus i dont say bad stuff. but alot of the time i get some of them thumbs down just bcus i dont agree with certain people. not my fault is i am smarter then them and make them look bad right? hah. but anyway can your answer go away on YA for too many 'thumbs' down? if so then i should really stop being right all the time bcus people dont seem to like it much huh
