How to track tumblr URL changes?

[Someone]

There is a blog that I do not wish to actively follow but I do wish checking it out occasionally, I do this by entering it's URL, the owner seems to like changing the URL once awhile, is there a way to know what the new URL is so I can continue viewing the blog?

No, I really don't think that's possible. The only way would be to follow them. If you don't want to follow them with your current account, you can always make an entirely new one and follow them with that one. And if you use a different browser when you log into it, you can stay logged into both your accounts at the same time.
