why are people allowed to send violation notices just because they don't like your answer?

Other users aren't capable of sending you violations notices, but they CAN report you if they don't like your Q&As. I knew what you meant though and I feel your frustration regarding unfair reports/violations.

Y!A's FAQ says that a question or answer will be removed if it's reported by one or more "reliable users." If the circumstance is more serious then the Answers staff may remove a question or answer themselves after reviewing it. However, the majority of the time they're just automatically removed and violation notices are issued, because of the way the Y!A system is designed. I personally feel the whole reporting/violation system needs to be changed because innocent questions and answers will be reported/removed while others, that are extremely offensive, are left alone. Also, I know that there are waaaaaay too many trolls disguised as "reliable users" who are out to get other users they don't like by wrongfully reporting them.

Furthermore, people who state their opinions are being reported as well. Y!A says that having a strong opinion is NOT a justifiable reason for reporting someone. They just ask that users "do not use slurs to refer to groups of people, do not insult other members, and do not act in a belligerent manner towards others" when stating their opinions. Unfortunately other users still do report opinionated questions or answers regardless of the fact that they don't violate any of the community guidelines. This is EXTREMELY frustrating because honest Y!A users shouldn't have to pay the price for report happy trolls!

They can do it if they don't like your question as well. It's supposed to be part of the "community" looking out for each other. Just like in a real community though, you have jerks, vandals, and "holier than thou" judgementalists, who just cause trouble and headaches for everyone.
