We know Shane as Pokeypony, AKA the zoophile that hooked up with Brandon "WILDWULF" Vongthongthrip and eloped to Arizona. He claims to be a former zoophile now, which if true would be quite something. Zoophiles very very rarely give it up cold turkey.
It's a pretty long and rambly message, but I am willing to believe it for now. It fits into the whole "just a bit too much effort to be BS" category.
One important thing to remember about sexual predators is that the smarter ones always make sure to target people who have imperfections that they can use - some dent or wound, no matter how superficial, that they can expand into an attack on their credibility. If Kamo is a fraction of the monster that Shane accuses him of being, then nothing he ever did to an animal matters that much anymore. Human victims must always take precedent over animal victims.
This situation is basically Sibe all over again, and it's why I'm not dismissing it outright. Sibe mostly went after other zoophiles, and uses his piracy infamy as a smokescreen. Only one victim ever came forward publically, but I know that there are several others.
It will be interesting if any others come forward in this case, but sadly the chances of that aren't too great. Shane does mention going to the cops, but, well, Arizona. 'Nuff said.
