I know diddley squat about goats, but generally, uncastrated males don't make the best pets. They have "urges".
Sounds like the whole point of the post was to deter possible buyers

But folk who don't know better sometimes buy animals on the strength of what the "experienced and reputable" seller is telling them, then it all goes t*ts up and it's usually the animal that suffers.
I have sheep and I'd never sell an entire ram as a pet. My ram's pretty docile and friendly but he does smell a bit and can be a bit "boisterous". Not pet material, unlike my wether.
I'm sure goatkeepers on here will have comments to make.
