WASHINGTON (WUSA) -- As Gaithersburg, Maryland resident Gary Giordano is being scrutinized by law enforcement in Aruba, other women have stepped forward to allege he has been violent with them and even, that he secretly videotaped their sexual encounters. Several say they met Giordano on the popular dating website, Match.com.
Match.com issued a statement to 9News, saying allegations like this between individuals who meet on Match.com "are extremely rare, but it doesn't make them any less horrifying." The online dating site also asks its members to report any suspicious or inappropriate behavior.
According to dating and relationship coach Michelle Jacoby, founder of www.DCMatchmaking.com, " In 2011, if you're not dating online, you're kind of a dating dinosaur."
The online dating world is wildly popular... and so are websites warning others of alleged 'bad dates' and suspected profile predators. Like www.Cheaterville.com and www.DontDateHimGirl.com.
Jacoby advises online daters to tell at least one friend the user name and phone number of the person you're meeting.
"You can say to your best friend if you don't hear from me by midnight, there's a problem and this is the person I'm out with and this is the number he gave me. So there's somebody keeping tabs on your safety that evening," said Jacoby.
You can also check websites like www.BeenVerified.com to find out in advance if a potential date has a violent history or a criminal record.
Said Jacoby, "For a small fee of under $100, you can do unlimited searches for a year. And you don't need the consent of the person. You can really search anyone. You can find out a lot of information about that person."
Also recommended: setting up a free Google Voice account, providing a phone number that can be used just for dating.
"You can give that number out when you're dating, so that nobody knows your real cell phone number. If that person starts to be bothersome, you can just block their calls," said Jacoby.
She also recommends setting up an email account that isn't your name and doesn't include any personal information.
