I don’t know anyone who doesn’t get a call from a telemarketer at least once a week if not much more. They’ll call and leave no message and annoy the heck out of you.
Unfortunately, some of these calls are actually made by criminals who try to get your personal information.
News articles over the past few days discuss about people trying to scam you out of your money or your private information. Scammers posing as US Department of Revenue employees, local bank employees, even police officers, have all been in the news over the past few days.
There’s a website called CallCatalog.com that uses crowd sourcing to grow their database of telemarketers. Crowd sourcing is basically when you, I, and everyone else go there and upload our experiences; it then shares it with everyone else. Sort of like a social network. When you go to their website, you put the phone number of the caller you want to lookup in the yellow box at the top of the page. It then presents information on what other people have written about these callers.
You can also post your own complaint.
Their blog also provides some additional information about how to deal with telemarketers and unwanted callers. Check them out.
