Sounds logic, but i don't know how to

Recently I’ve been thinking of making a new blog about a game I usually play, but the link, i mean the URL is already taken by somebody who doesn’t use the site anymore. (I mean it got no posts and it was made in 2009). Does there exist any way to delete that old blog and make a new one instead? (I’m not the owner of that blog).
Please reply asap.

(or my 2nd idea was loll.wordpress.com, but this is the same situation as above)
