The herd mentality over at faucethub these days seems to be 5 mins 20 sats with a recaptcha and/or a shortlink.
Horrible and brainless.
If you could make your faucet at least slightly unique it would be a huge improvement.
Loyalty bonuses, a lotto maybe, interest rate for holding satoshis on your faucet for X time, a pvp card game.
If I had the time and resources, that are some of the things I would do.
I take back what I said about garbage. That's just what we have been seeing to no end as of late.
I can see you are at least trying
Good luck.
