These modes of addressing are perceived as ugly forms of saying things and their message seems uninteresting or bad and ugly for this formal and civilized society.They say/revealing/mediating things that are unacceptable by the society/ unspeakable, political incorrect, emotionally overwhelmed, disorderly.
At the same time because of their ugliness they are suppressed and accused as ugly forms. They are unfiltered, unedited messages/content that overpass the rational sphere of speech. They are too personal, too emotional, too embodied. From my perspective the medium they use and the form they take also affects that character. Most of the times those mediums are characterized by instant communication, liveness, hit and run, fast/urgent communication (from Multiplication...). Streaming is one concept example.
