The original poster was legitimate, but it was basically impossible to tell with their writing style. The ones afterwards were bits though. I mean, read this, it absolutely sounds like a bit:

" Lol seriously? Are you trying to brag about that? That will never be the same. Try all you want. Doll you partner up in a head to toe Zootopia Bunny fursuit. It's still just your partner in a fursuit.

You can close your eyes and pretend it's Lt. Judy Hopps whose fur you're digging your nails into. But it's not. It's some stupid human in a costume. And no human will ever be able to scratch the itch you're trying to reach.

You think you're better than us virgins because you can ever so temporarily convince yourself you have access to a fantasy we both know you don't? Pathetic.

You have a choice to make right now. Good or evil. Nirvāṇa or Saṃsāra. Either accept volcelibacy, and with it the truth that your fantasy of fucking like rabbits will never come to literal fruition, or go back to your lies and have fun falling asleep every night fighting tears as you catch a glimpse of your wife's silhouette in bed and realize it will never sprout bunny ears."
