The full website uses AJAX. Switch over to the mobile site for scraping the infos.

How about adding cmd/faucet/faucet_test.go:

package main

import (
	"fmt"
	"testing"

	"github.com/ethereum/go-ethereum/common"
)

func TestFacebook(t *testing.T) {
	for _, tt := range []struct {
		url  string
		want common.Address
	}{
		{
			"https://www.facebook.com/ambreen.fatimah.1/posts/781618749097122",
			common.HexToAddress("0x956Bcb03a6f8Df9566C7b300E35A21571e30c559"),
		},
	} {
		_, _, gotAddress, err := authFacebook(tt.url)
		if err != nil {
			t.Fatal(err)
		}
		if gotAddress != tt.want {
			t.Fatalf("address wrong, have %v want %v", gotAddress, tt.want)
		}
	}
}

( the reason I haven't pushed it as a commit, is that it would be better to use facebook-posts that aren't just random people, but people who are already affiliated with go-ethereum. I don't have a FB account personally... Although, hold on, I do have an account or two..)

Ok, this one should work:

package main

import (
	"testing"

	"github.com/ethereum/go-ethereum/common"
)

func TestFacebook(t *testing.T) {
	for _, tt := range []struct {
		url  string
		want common.Address
	}{
		{
			"https://www.facebook.com/fooz.gazonk/posts/2837228539847129",
			common.HexToAddress("0xDeadDeaDDeaDbEefbEeFbEEfBeeFBeefBeeFbEEF"),
		},
	} {
		_, _, gotAddress, err := authFacebook(tt.url)
		if err != nil {
			t.Fatal(err)
		}
		if gotAddress != tt.want {
			t.Fatalf("address wrong, have %v want %v", gotAddress, tt.want)
		}
	}
}
