Product unavailable for review

I'm new to this and I can't seem to find the answer to my question which is, if I get this when I ask for an assignment

"Free assignments are not available for products with 3 or more assigned reviews or pending assignments."

Does that mean this product will never be able to be reviewed for free again or will it eventually become available again? less

If a product already has 3 or more assigned reviews, it will never be available to be reviewed for free again unless there is something special going on, like a manufacturer who would like this product reviewed and supplies EF with some for review (which would be a manufacturer sponsored review). less
