If you want to limit by IP, add in this code or check out & switch to limit-ip branch (add in your index file & changes) https://github.com/KeepBitcoinFree-org/slp-faucet/tree/limit-ip
no video tutorial as of yet. It's not hard though. Literally just add that highlighted text into your server.js file, then rebuild with 'tsc' and restart your node.js slp-faucet
