  I visited the old Galaxy Zoo forum and searched for the DR7-ID 587732589572325457. It had been posted in the topic "Possible lenses".: There are following comments (in two separate posts) by GZ scientist Aprajita!

  this does look like a possible lensing event by a group of galaxies.

  (...) in my list of high probability candidates.
