Much as I dislike Facebook, I wish...
I actually wish that Facebook hadn't dropped the ball on this one. All they needed to do was offer a superior email alternative.
Hint: Less SPAM.
What if Facebook had offered an integrated anti-spam fighting system? Not a lynch mob tool per se, much as the spammers deserve it, but just a way to help with the best targeting of the anti-spam countermeasures. Don't you wish you could help break ALL of the spammers' infrastructure? Help pursue ALL of the spammers' accomplices? Help protect ALL of the spammers' victims (from their own stupidity in giving money or personal info to spammers)? No, we can't eliminate spam, but with better tools we could reduce the spammers' profits. The spammers still wouldn't become decent human beings, but they would move under less visible rocks.
Too bad. Facebook actually had a chance to make the world better, in stark contrast to whatever it is they think they are doing now.
