How do I start a commercial newsgroup?

In 1998, Deeter was at the center of a Usenet controversy involving the commercial trade of stamps. When a proposal to split rec.collecting.stamps into separate discussion and marketplace groups was brought to news.groups, Deeter launched an unusual campaign to retain the status quo by offering $50 worth of stamps to people who would vote against the split. The newsgroup vote, having been tainted by apparent vote buying, was invalidated and retaken.
