Random project idea I'll problem never get to but maybe someone else would like to do:

Testnet or signet faucet nostr bot that keep track of if/how much test coins your npub has requested, contributed and/or returned. Require some sort of npub PoW for new account requests or follows by other well behaved accounts. Could also require answering some random bitcoin history and/or dev protocol trivia questions. Could publicly shame users who receive coins but never return any. Extra credit if bot also supports LN.
