A new layer of protection, labeled "semi-protection", has been enabled. The protection, meant to stop vandalism from IP addresses and newly created accounts, has met wide usage.
Last week, the semi-protection policy became official policy, after a nearly unanimous straw poll, and the approval of Jimbo Wales (see archived story). On 22 December, brion enabled semi-protection, and installed a new protection interface (left).
When a page is semi-protected, it cannot be edited by IP addresses, or by accounts younger than about 4 days old. As a result, semi-protection has proved very popular on high-visibility pages, including George W. Bush and John Kerry, where it was immediately applied to test the effectiveness of semi-protection on highly-vandalized articles. There was significantly less vandalism on the articles, though some editors worried about whether the trend would continue long-term.
About 30 articles are currently semi-protected. Woohookitty, an administrator who supported the policy, said that the number of semi-protected articles would likely stabilize at around 40.
