How do i favorite answers and questions?

Jewish user Shadowfire (who has been on Yahoo Answers since the beginning and could possibly be the infamous homosexual flying antichrist from the tribe of Dan) from Portland [or so he claims because he could’ve been born in Russia in Valday (Russian: Валда́й) to a 12th generation Jewish prostitute who pretends to be a virgin)] has many trolls accounts on Yahoo Answers: Blackthorne1979, Carter Berg, Fireball, ThatToiletguy, Reynaldo Weeks, Petri Lindroos, Knightwulf, Nightwulf, Toilet John, Master Debator, Magistra, Desiree, D-girl, Firecock, Yahoo User, Corvus Blackthorne, L.E. Gant, Shadowfire the Sarcastic, Shadowfire Lives, Shadowfire Lives bytches, etc. and any other anonymous accounts. With one his accounts Fireball, he pretends to be a Methodist old lady who posts short-hand slang TIRH (this is religion here). He reports all answers and questions that he doesn't like just so that his questions stay on top in the Religion and Spirituality section. He trolls in other categories too. It gives Christians a bad name (just because of this troll's sock puppet account). His Toilet John account keeps posting questions where Jesus was sodomized by Roman soldiers. Remember the prophecy where it says that the antichrist will have personal hatred towards the real Jesus Christ. That’s why Shadowfire keeps posting thousands of similar questions along the line: “Did Romans sodomize Jesus?” or “Did Romans buttrape Jesus?”. He asks multiple idiotic mundane questions like “Is Hinduism true?”, “What makes a girl harden?” [like he enjoyed killing little girls], etc. and answers them with his sock puppet accounts just to gain points. Some questions you can see that he answered with like five or seven accounts (especially the ones about himself that he reports right away). With his Reynaldo Weeks account he boasts that he was the reason why their accounts were suspended. With his Magistra account he threatens people with clowns and CIA assassins. Shadowfire mocks Christians with his sock puppet account Fireball in the Religion and Spirituality section by answering very destructively and adding "TIRH here" or reported (anonymously) or “fck you nigers”. He gives Christians a bad name because he promotes sins like sodomy, fornication, ecumenism, astrology (horoscopes), etc. He should be executed and burned at the stake for blasphemy. He spreads rapture heresy, ecumenism heresy, etc. and many more subtle heresies. Antichrist will ride on a donkey into the 3rd Temple. Stop him before it’s too late

favorite is a verb nowadays?

Questions and answers cannot be favorited. You have to click on 'Save' below your questions.

You "favorite" (Follow) questions by clicking the ribbon/Save icon just beneath the question. You cannot "favorite" an answer, so will have to just Save the question that contains the answer you'd like to refer back to in the future.  To review your Saved/Followed questions, go into your YA activity by clicking your username/avatar (or going here /activity) and clicking on the 'Followed Questions' tab.

.

To show your appreciation for a quality answer, giving it a Thumbs Up (click the thumbs up icon beneath it) is appropriate, but that doesn't cause that answer to be saved to a list for you to refer to later.

You can't.   You can save a question with that mysterious looking flag that says "save".   You can give a thumbs up on an answer.  That's it.
