I tried to find an answer to my question on the forum and they sent me back to you.
time ago I deleted (mistakenly) my blog signorinaperditempo.wordpress.com and now the link is no longer available. can be recovered in some way this url?
There is no way to recover the URL your deleted because there is no recycling of deleted blog URLs here at WordPress.com. This prevents the scenario of someone impersonating the blogger who originally had the deleted URL after they deleted it.
There are 3 warning of this given prior to blog deletion and then a confirmation link in an email is sent, and the blog is not deleted until that link is clicked. That prevents accidental deletions by insuring everyone who deletes a blog has had lots of previous warnings that what they are doing is irreversible.
