A seemingly innocent website knows who your family members are and where they live

There's a lot of information about you in public documents if you've ever signed a lease or applied for a loan - your address, your age, sometimes the identify of your family members.

It's well known that a lot of sites around the internet, such as Spokeo, collect and compile that kind of information into databases.

But one innocuous-seeming website, FamilyTreeNow.com, found itself at the center of controversy earlier this week when some people realized that you could get information like a person's address, family members, birth month, and phone number - within minutes and without ever creating an account. 

Go check it out for yourself. Simply input your name and your state and see what it turns up for you. For me, it found my immediate family members, an old address I used to use, and my current address. 

Anna Brittain, a young-adult fiction writer based in Alabama, discovered Family Tree Now, and tweeted out a series of instructions about how to remove your personal information that ended up going viral. 

Her recommendations were picked up by The Washington Post, and several Facebook users, and Snopes eventually had to run an article to clear up misconceptions. 

"Internet safety is important to anyone, and in particular the community I belong to on twitter sees a lot of targeted online abuse. Thanks to a volatile political climate, using our voices now comes with placing targets on our backs -- particularly the marginalized groups Tr*mp has alienated and endangered most," Brittain wrote in a blog post published on Thursday.

The good news is that Brittain's instructions about how to opt-out are clear and effective. I was able to remove myself from its database quickly.

"DUE TO HIGH VOLUME, OPT OUT REQUESTS SUBMITTED HERE WILL BE SEVERELY DELAYED!!!" according to the FamilyTreeNow website. A request for comment was not immediately returned. 

Here's how to opt-out:
