Is this griefing?

Hi guys i need an opinion in one of my latest matches. I played as Zeus and had a really bad game, made many mistakes and was underfarmed. But the thing that annoyed me the most was our carry dusa. She basically afk farmed for 40 minutes. She wasn't even hitting ancients most of the time, only the top dire jungle. Would you guys consider this griefing? I felt like he could have joined us many times while fighting. It was an unranked game btw, and the Tinker Player is a new account/smurf with +80% winrate. If somebody wants to check out the game here is the Match ID: 7581763551
