I have an account with WordPress, but have not used it in years now. If I click on the page it will say that I do not have a site any more, which is OK. My question is can I start all over with this account by changing the name and domain?
Your account indicates you don’t have any sites, because the site you used to have with us was suspended almost 9 years ago. Accounts with a suspended site do not have the ability to create any new sites. If you have any questions about the suspended site, please use the form at https://en.support.wordpress.com/suspended-blogs/ – we cannot help with suspended sites here in the public forums.
If you want to start a new site on WordPress.com, you’ll have to register a brand new username account by logging out of this account and visiting https://wordpress.com/start/site/
If you want to close this account before creating a new one, you can do so from the account settings page.
