When registering to vote, do not put your email address.
I got spammed today by some podunk political campaign for their candidate. At the fine print was this:
“A message from Winvotes.com This email is being sent to you because you voluntarily listed your email address on your voter registration form, which is public information for political campaigns, journalistic or educational research.”
Update: Another lesson to never make your email publicly available anywhere. It’s ridiculous how spammers are able to get at us – perfect market theory must be. Makes me want to go out and vote for his opponent just to cancel out one of the votes that he gets.
