ACT are definitely up to no good with their lists.
Having unwisely filled out a survey for them last election (or possibly even the one before) I still get emails from them. I unsubscribe (sometimes using swear words) but a few months later I'll get an email from a particular ACT MP or electorate office. So I end up having to unsubscribe to every email that they send.
Then last week one from ml-ingenious about Roger Douglas and the second coming.
Then I got one from a National MP recently - the only way I could think they'd get my address is from ACT?
If anyone can give advice on how to get off their list for good - it'd be much appreciated!
