They are the links to the images I uploaded to twitter when I made the tweets, not links that I typed in. I haven't checked if they work; I just assume that twitter got rid of them. The sli.mg links are shorter and easier to type, and having the old links struck out is an easy way of saying "don't bother with the old link, follow this one." Good question.

Why would you even want to be on twitter? Pretty much the most corrupt site you'll find. Worse that Reddit, Tumblr, and Instagram combined.

Its the world power structure protecting the world power structure.
