what many see as trolls are in reality carefully constructed efficient rhetorical devices engineered to circumvent traditional cognition of textual communication through the utilization of textual communication itself. it is in this juxtaposition of normally disparate forms that the intended message is conveyed to the reader, who when presented with these rhetorical devices, are forced to decode, confront and absorb not the words themselves, but the semiotics, etymons and meta-contexts of the words.
