"Dear community. I need some hive justice. I'm facing a lawsuit for $18,000 from a stock photo site that claims I stole one of their photos, when in fact they stole it from me!"
"Oh man, James had so much crap done to him IRL after he posted that YouTube of him abusing a cat. That's some hive justice right there."
