How does this work?

This Ether faucet is running on the {{.Network}} network. To prevent malicious actors from exhausting all available funds or accumulating enough Ether to mount long running spam attacks, requests are tied to certain common 3rd party accounts. Anyone having a GitHub, Twitter, Google+ or Facebook account may request funds within the permitted limits.
