Sweepstakes Ninja | Winners List, Forums, + More!

No one I know on any of the two sweepstakes boards have won this sweepstakes. I keep deleting them from the Ninja sweeps, only
to have them show up again the next day.

How can we delete permanently these sweeps? Or would the owner of the site, place these sweeps together, so I can do a bulk delete instead of small batches (up to 8) daily???
