Typically, we call them bots. Usually they are programs made to spam this shit. On the rare occasion it is actually a real human behind the wheel, so to speak, it's one that obviously doesn't care about getting their account deleted, as they just make another account under another proxy.
Hey there Great work so far. I really like the middle- and the background but I think that the foreground would welcome a higher contrast. Due to the low contrast the foreground looks really "photoshopped". It cuts the picture in two halves. The looks much more interesting which disturbs me in some way but I haven't said anything if that was your intention^^ Everybody has the own taste
