[i only sound smarter than I really am. I saw the post, and it
  had the "feel" of a hit-and-run poster. I looked up Senna
  Persson, first on group - not there. Then on Google, saw a
  Swedish actress, then realized my first inkling is likely
  correct: hit-and-run poster. I actually find their scripts
  impressive - the ones that create / delete accounts on a
  monumental basis in order to keep a few steps ahead of online
  tracking systems.

  But of course it's annoying when you want to have a two way
  conversation. They pop in, leave, change accounts, move on to
  the next location.
