I don't really scam those kind of people but I would rather waste their time so they would also be frustrated for a bit or couldn't scam others while talking to me.
I once received a message asking for help pretending to be someone I know so I just continued to have the conversation and play dumb,
Till the scammer got irritated on every question that I asked back,
I really had fun wasting the scammers time since I don't have anything to do at that time so I just played along to enjoy it.
