The sites charge .99 for a month's membership or 1.94 for six months, prices set by Friends Worldwide, according to the service.
Emails to various addresses associated with White Box and Friends Worldwide went unreturned Monday.
The Riddlebergers have been active in Guilford County Republican politics over the years.
Russian and Ukrainian women are known to be not only feminine and charming but faithful wives and the most loving mothers as well.
The site has gotten some media coverage recently, primarily because it's designed to serve only straight people, letting people sign up only if they choose "straight man" or "straight woman" at the outset.
Some reports have also noted that, once a person gets past the initial sign-up page, he or she can choose "happily married" or "unhappily married" as a status before finalizing a profile and meeting new potential dates.
The charge stemmed from his videotaping himself having sex with a 15-year-old girl when he was 25, the Greensboro News & Record reported in 2014. A press release announcing the site's creation and a paid-for blogpost on the right-leaning Daily Caller website circulated within the past few weeks quoting a Sean Mc Grossier as the website's founder and owner. The site is part of chain of dating sites tied to Friends Worldwide, which owns an entity called White Box Dating.
A North Carolina criminal history check Monday turned up no serious charges on Riddleberger's record since then. "I've already paid my debt for something I did 25 years ago," he said. White Box lets people create their own niche dating websites, providing the template and technical support for an initial fee and at least a 50 percent commission on gross income, according to the service's website.
