Have you ever considered a quickie feature to post an image on the site that's already in the comments, but it also functions as a link to take you to that image?
Basically a version of this: "!https://derpicdn.net/img/view/2013/3/14/270072.gif!":https://derpibooru.org/270072
Condensed into one line of code like (for example) this: >>>270072
Or whatever works?
So far the closest we can get is the long string of code above, and since that rigidly takes you to one specific booru instead of whichever booru whoever clicks the link is using, it messes people up a bit. Like, if you posted a link with that code using derpibooru.org and along comes a spider who is using derpiboo.ru, it will mess them up.
