The REST verb TROLL questions the veracity of a URI as it presently stands. It amounts to a simple tag indicating "someone has doubted this", or calling for additional authority. For instance any issue/position/argument trolled should be augmented to add more evidence/source/authority.
In trollish, the verb to troll means the same as the verb to be: any time any living being does anything visible or described using symbols, it becomes trolling simply by being posed in a frame and continuing to exist and evolve beyond the restrictions of that frame. See contestant should always switch. This usage highlights the difference between being and description: Life forms, simply by existing, challenge the models and simulations of their existence.
In English, the verb has many meanings including singing loudly and repetitively, annoying others deliberately (by any of those means), fishing with a hook. There is even a reflexive verb form, see self-trolls phenomena. It is also common to associate the verb with the supposed actions of ancient pre-human beings who challenge human authority, especially Christian authority - this follows usage in Norway - see Norwegian mountain troll - and Sweden - see trollkonor.
