More spam than usual at wikinews

On normal days, the amount of newly created articles at Wikinews is low. Each day around 2-3 spam pages were created by random ip adresses and it takes around 30 minutes until the admin deletes the content. But today something is different. According to the recent changes tabes around 7 pages which contains obviously spam were created this morning, but the admin doesn't react. The newly created pages are in the system. Like most of spam articles they didn't have references at the end and containing one or two paragraph with a poem or lorem ipsum test messages.

UPDATE
Most of the newly created spam pages were deleted by the admins. In contrast to the normal admin behavior the duration was longer. It took around 5 hours between creation of the page and the deletion.
