It is not now and it has never been acceptable to delete articles that have no references just because they have no references, nor to nominate articles for deletion on that ground alone. You need to know that it is not verifiable. There are only two ways you can say that: first, you made a good faith effort appropriate to the article and failed. The other if it is obvious from similar cases that the material is totally unverifiable.
There's a loophole here: Just delete paragraphs from the article on the grounds of having no references. Once the article's almost empty, then nominate it for deletion.
