EBay says it is monitoring listings to ensure nobody uses the auction website to profit off the Boston Marathon bombings.

Remaining up is a medal from this year’s race whose proceeds will go directly to charity.

Jonathan Resnick says when he read on a runners’ discussion board about people selling their medals, he realized “it was the least I could do to make something good from something bad.” The winning bid for Resnick’s medal will go to the American Red Cross of Eastern Massachusetts through eBay’s program for charitable giving.

EBay says its policy “does not allow listings that graphically portray, glorify or attempt to profit from human tragedy or suffering.”

Boston Athletic Association spokesman Marc Davis says: “What people choose to do with their medals is, and always has been, their prerogative.”
