The Harry Potter Automatic News Aggregator site folks have decided to cripple the functionality of their own website in order to avoid spoilers of the 7th book in the series getting posted there.
"we've implemented a comprehensive set of protection policies for Deathly Hallows, which are now live.
Unfortunately they are rather strict and cripple much of the site's functionality, but we would like to err on the side of caution rather than convenience. As such, members who joined after July 1st, 2007 or who have less than 100 points will not be able to post in HPANA's forums at all, effective immediately. External images and links have been disabled until after the book release, and the Wizard Wire Service on HPANA's home page has been temporarily removed.
We hope these and other minor changes will help ensure a spoiler-free experience on the site for the next several days before the release of book 7. Following its publication, HPANA will close almost completely for approximately 48 hours.
Please don't hesitate to contact one of the moderators if you find something spoilery anywhere on the site.
Also note that any spoilers (scans of the book, chapter or plot summaries or elements) prior to its official release at 12:01 a.m. on July 21 will be removed and the poster's details, including IP address, will be forwarded to the Harry Potter publishers and JK Rowling's office. (Not to mention, banned from HPANA.)"
