twitter should stop shortening my URLs

I wonder, why twitter shortens URLs at all?
(i know, this has already been asked, but hear me out)

In my opinion, there's no gain in shortening URLs. Sure, tweets are meant to be short and limited to 140 characters. But shortening the URL doesn't help here. Links are not shortened while you type them but after you already sent your tweet. This means, your link already fits into the 140-character limitation - why bother shortening it?

If I need to get a long tweet AND a link in there, I'll have to shorten the link manually - so shortening is really never helpful.

On the other hand, these urls are dangerous for three reasons:

• You don't see (immediately) where they lead. http://tr.im/my-short-link could lead anywhere from News to Porn.


• Shortening Services may one day shut down or change their url-scheme. You could never restore a link in this case [1].


• Shortening Services have been hacked before [2].

Twitter: Please give me an option to turn off shortening once and for all for my account. I don't want it, I think it's unnerving.
I also think it is a problem, so i marked it as one. If you think, shortening is a bad idea, retweet this with #stopshortening or add yourself to "I have this problem, too"
