I hope the horse I am beating is still alive: we have to be absolutely ruthless about removing "I think I heard it somewhere" pseudo-information from Wikipedia, and especially from biographies.
People who are fighting the good fight here are sometimes threatened with a trip to ArbCom. They need our support, though.

It needs to be clear up and down the line that the arbitration committee will support people who remove unsourced information, as long as they are nice about it. But these things should never come to us, people who resist removal of unsourced information should be clued in long before it comes to that.
