With hundreds of thousands of combination or even millions, I don't think anyone can guess the right 6 digit code after I guess I was redirected to a faucet where I can claim 10 sats for every 30 minutes, not an attractive way to invite people as it's impossible to guess the right 6 disit code it's just a cloak so you can invite people to join your faucet.
Yeah, you're right. It was a blunder to invite such people like this way. I think the 6 digit code puzzle isn't very trusted at all, Do you(the admin of his faucet) have the list of users who've guessed the right 6 digit code?
