add PoW testnet faucet
Maybe use a testnet bitgo wallet?
Limit to one withdraw per IP address per day
Great idea
Look into using BTCPay Server's new "pull payment" functionality. Still need to put it behind some kind of PoW wall

Target 10 min PoW Always send 0.01 to avoid dust / edge cases

supporting signet would be a nice bonus
