Previously, I paid to have my free WP.com blog have a custom domain (justbcause.com). Recently, I chose to instead have that same free WP.com blog have a different custom domain (rachharris.com). It has, however, come to my attention that my blog's content is being used at the old domain: http://justbcause.com. How do I prevent my content from appearing on that old domain?
Thank you for the help!
The blog I need help with is rachharris.com.
