If you come across a photo of Bill Gates on Facebook that says he'll give you money if you share it, don't fall for the trick. There's no harm in sharing the photo but it won't get you $5,000 since it's a hoax.

A photo started going around on Facebook of billionaire Bill Gates holding a sign that reads  "Hey Facebook, As some of you may know, I'm Bill Gates. If you click that share link, I will give you $5,000. I always deliver, I mean, I brought your Windows XP, right?"

You can share the photo all you want but the man behind Microsoft isn't going to give you a dime.

Gates did pose for a photo in which he was holding a sign but it was part of Reddit's Ask Me Anything section. Reddit IAmA gives celebrities or a well-known person a chance to talk with Reddit users in a forum. Users can ask the person whatever question they want.

Bill Gates had an IAmA session on February 11.

In his IAmA post, Gates said "Hi, I'm Bill Gates, co-chair of the Bill & Melinda Gates Foundation. Ask me anything.

Many of you know me from my Microsoft days. The company remains very important to me and I'm still chairman. But today my full time work is with the foundation. Melinda and I believe that everyone deserves the chance for a healthy and productive life - and so with the help of our amazing partners, we are working to find innovative ways to help people in need all over the world.

I've just finished writing my 2013 Annual Letter https://www.billsletter.com. This year I wrote about how there is a great opportunity to apply goals and measures to make global improvements in health, development and even education in the U.S."

He then posted a photo to verify that it was indeed him talking to users. The photo below was then altered by someone who turned it into a Facebook hoax.

Some may share the photo as a joke, knowing that it's fake, but other users are sharing the photo in hopes that they really do receive $5,000.
