Hi Carol. I wanted to change some poducts on a hub the other day and was advised of this new policy, but as far as I can make out it´s all to do with overuse of keywords. The hub was about how to grow your salad and veg in a small space- container gardening, and I had selected a lot of amazon book with the title.. container gardening hence the warning. So I selected only 2 books with this title and added gardening tools and equipment instead and as far as I am aware all are advertised and have been accepted on the hub. I am just going to check and will be back with you in a minute.
Yes I just checked and all the amazon products I chose without using so many keywords are there on the hub.
