Now I got it that why the user was asking for Testnet coins. I thought they might be doing something good but all they want is that airdrop of NFT. I agree that now Bitcoin is getting attacked by those NFTs and Ordinals from all sides.

Those guys have not started attacking testnet coins which have no value at all and are mined for testing purpose only. So, I guess OP will surely get bombarded with many messages and requests because he's offering free testnet coins to users.
