Clicking on the Family Filter button in the Dailymotion header to change your status should let you switch it off, but currently only results in a "page not found" error. Even if you change your default location, the problem remains, suggesting that either Dailymotion is using IP address filtering or that there's a much broader problem with its site. Australian users have been complaining on Dailymotion's own blog, but that doesn't seem to have had much effect so far. Offering a filter is a better solution than YouTube's "ban anything adult" approach, but pretending to offer one isn't. Thanks RC for the tip!
