I can’t say that this person is lying, but there is no aspect of  a neuter that would render a bun paralysed. A rabbit neuter is minimally invasive, the bun is put under and the incisions made are nowhere near the spinal cord. The neuter only involves the testicles, which are not even inside the abdominal cavity.

If a bunny comes back paralysed sth else has happened, f ex a drop from a table or a person’s arms.

That said, sometimes people aren’t completely fair in their reviews. They can be upset or feel vindictive for some other reason.

Again, there is nothing in a neuter that could cause paralysis. The bun is under general anestesia, not an epidural like a human giving birth. The vet puts sterile surgical sheets around the testicles so only the testicles are exposed. They then apply a disinfectant (often povidone iodine). Then they make tiny incisions or, in some cases, only one incision through which they access and snip both testes. The testicle sacks will shrivel up snd become unnoticable spontaneosly with time, so they dont cut them off or antthing, they just leave them be. There’s no way the lower spine could suffer any type of damage through this procedure.
