Other way:
there are those smart contract wallets where there are 1000's of dollars, but no ETH for the fee. You voluntarily give seed phrase to the scammer, and when they send ETH for the transaction fee, that ETH gets redirected to void or your wallet.

And when you're done with it what will you call yourself then? If you should carryout something like this it means you're no different from the scammer so you should also consider yourself a scammer also.
The best thing to do is to take precautions and avoid been scammed rather than trying to outsmart the scammer, something could go wrong and you might loss your funds.
