how about storing trusted tripcodes in cookies? you would add one by clicking on it, thus changing it's color or whatever.
That's more or less the principle of the world2ch capcodes, although those had to get registered with the admin of the site / network.

It would be harder to quote them... I can copy-paste "hotaru!hoTarufiRE!!H0csnvz2" easily but saving and uploading an image would be more annoying, and you couldn't type it yourself or search for it (eg. on Share) easily.

Maybe someone could write a firefox extension that keeps a list of words you specify and highlights them wherever they occur in web pages, like how google's cache highlights your search terms.
