This would be begging: "please, please, please fav the article, because the fairies told us to post it and they'll kill us if we don't have 50 favs by midnight and *TheOtherSarshi is from Romania and has 1:30 hours left until then!"
And this would be threatening: "Fav, or the kitten gets it! We have dragons and robots - it will never stand a chance! Mwahahahaha!"
And this would be the best way to go about it: "..." *creepy smile* *ghosts pop around reader, hovering and staring in perfect quietness* *a choir of little boys starts singing 'Hallelujah' right outside the window, but they sound very far away* *breathing on your neck* *the news article shows up, written in blood, while your hand moves forward to fave it by itself and you know, you really know, that if you don't manage to fave it soon, you'll never wake up...* *you realize that there is no mouse and there is no keyboard; the seconds until the option goes away are ticking away, away, you open your mouth to scream and no sound comes out, but you want to fave it, you do, you do, and then...*
*you wake up and see that you're still in front of the screen, there's a mouse, a keyboard, and a link to the article*
...erm. Sorry. My imagination got away from me. O_o
