why does yahoo answers keep deleting things at random?

They don't. Without more details it is impossible to know as to why your question(s) was (were) deleted, however this may be of some help it is long but covers most everything.

Questions without answers are removed by Yahoo after 4 days 8 if you extended it or no best answer" won the vote. You don't lose any points.

If you received a violation notice and sometimes you don't : All it takes is 2 "trusted" members. in rare cases only one to report you and the bots remove it. If you are very sure you have been wronged appeal it, the link is below. Some suggestions, If you haven't done so, edit you info so your questions and answers are hidden that way it makes it harder for trolls who enjoy reporting violations or presumed violations to stalk you. Also, avoid pages with controversial subjects such as religion, homosexuality, racism, pornography, any hatred, downloading movies or music, questions about drugs even soft drugs, etc. Even the polls section. Avoid anything that may be remotely considered illegal, talking suicide or threatening others. Don't give smart, flip or sarcastic answers nor use any profanity. Do not use language you wouldn't use when talking to your grandmother and that should keep you safe in that regard. Referring to others as a moron, stupid idiot Nazi, retard or anything in that vein is derogatory and insulting to other members and clearly against the guidelines. Ensure that your links aren't interpreted as spam that's against the guidelines. Pay attention to the definitions of "chatting and solicitation , and what constitutes a question" Never insult another member, threaten, harass deliberately mislead or post anything in questionable taste. If you admit you are under the minimum age of 13 chances are you will be reported.

i comprehend that surpassed off to me in the previous i asked a query and it have been given deleted for some reason and that i did no longer say something undesirable in any respect it become just about black Friday yet then somebody sent me an e mail asserting they reported me as an abuser so it become in all probability an analogous for you people do exactly that because of the fact they are stupid

they delete questions and answers when enough people report them or when someone with more influence reports them. this is a stupid concept considering a lot of trolls report people at random. you can appeal if you think they were wrong and you'll get you answer re-instated, but a lot of people don't bother with it.

i had a question deleted this week and I havent a clue why.

i felt annoyed that a perfectly innocent question had been removed for no reason at all.

it had been starred by two people, so they found it ok.

It's also possible that the asker (him-or herself) deleted the question.
