Pretty sure quite a few people saw those details, there was a link to it on this forum and some other forums, this was all about ten days ago.
No issue with that if it was only names and addresses. You can in any event find this type of information freely over the internet. Just go to your local city council and do a valuation roll lookup. Go to the white pages and enter a surname and town. You will get names and addresses and there are no law preventing this information from being displayed.
