sloppers can just keep burning new accounts (as long as they have access to new IP addresses) while real developers deserving of praise and reputation thrive.

Becoming a Debian developer requires you to meet an existing Debian developer in person and have your public key signed by them. It's not possible to keep burning new accounts unless you go and meet a different Debian developer each time and there's a limited number of them in each region and they usually meet together, so more than one person will see your face.
