I must have just read your post just as some cosmic ray hit a nerve cell in my brain scattering electrons willy-nilly and setting off an a cascade of thoughts, weirdness that took the following form: If it waddles like a duck and quacks like a duck, it could be a human impersonating a duck. What possible relevance that could have to anything here, I have no idea.you're not a concern troll. you're a literate russian bot.
