The person who created the post on Facebook gets paid a commission when they get new users to sign-up.
The problem with these ads is many people believe they are real business models because Facebook allows them on your News Feed.
You might see a "Suggested Post" on your News Feed that promotes Binary Options, a get rich quick scheme.
Here's an example of what it looks like: These Binary Option schemes claim to have the secret to getting rich from certain stock investments.
The post claims that doctors are telling patients that the pill contains the "Machupo" virus and is one of the most dangerous viruses in the world.
Now, we're not talking about a computer virus here, we're talking about a virus that a human would contract.
However, financial experts say unregulated investment platforms like this are more like a form of gambling and not actual investing.
Many of these work-from-home posts are just scams, trying to convince users to open an account with a specific broker.
How the scam works is, the victim receives a message warning them that their Facebook account is going to be disabled.
The reason is that someone has reported the account as violating Facebook's terms of service.
