Deleting things at scale is hard. There are good technical reasons why associated data (the short URL and the image) wouldn't be deleted at the same time as the tweet. If the link and the image are still visible in a few days time <i>then</i> I'd be concerned.
Well, here's the thing. I create a service that actually deletes the content, yet someone else who had access to your tweet/post saved a copy of it - through a screenshot, a backup, copy/paste. Should they allowed to have that? Are they allowed to take a pencil/pen and write down what you wrote, so they can remember it for themselves - and reference it later?
