The second thing is not an ad hominem, it's talking about what he did or how he did it, not who he is.
“An Ad hominem refers to when a speaker attacks the character, motive, or some other attribute of the person making an argument rather than the substance of the argument itself”
It’s definitionally an ad hominem against Jared. If he stuck to why he thought it was bad for Bun to do this, I would be more sympathetic.
Casting aspersions without proof, even if it's something everyone knows, is in poor taste and ad hominem. I've never heard a bad word about Jaredd before, so Andrew seems more like a stinky person to me right now.
