Here's a better idea: instead of ranting, how about just reporting someone you think is an obvious troll? Mods tend to delete the worst posts, issue warnings, and even ban people. mvqulik, I thought you knew better by this point.
Back on topic:
Rabbits like to hide behind trees and other objects (they tend to get stuck on them when moving from place to place). That's why it's recommended to get Ender's so you can hide the trees, rocks and flora. Still, I've gone a couple hours without rabbits or chickens. It happens. I've had other times I've gotten half a dozen rabbits in 15-20 minutes.
