...the browser will automatically redirect to another page where you have explained why you are disallowing url shortened links to your content.
If you're going to the trouble of serving up content from your site, why would you disallow the content they came to see anyway? Maybe the concept could work if you had support from higher-up in the redirection process (from url shortening services themselves), but to effectively re-direct from your own page to another "you an't access this content" page on your site will only make end users confused and disinterested, driving traffic away.
I agree that URL shorteners are bad and acknowledge you're trying to do something about it, but this isn't the way to solve the problem.
