We dealt with multiple con artists trying to scam us (AirBNB is full of transient people using the service to try to con hosts).

With some of these videos produced to get your attention, I honestly thought it was a scam.

In case you're interested I detailed my experience on a different thread entitled "Suprising how little discussion of RE scams here".  

Your aunt Millie, may think you offering her 8% is a scam.

Unfortunately, the one thing that wasn't fabricated was our address.Clearly these villains are attempting to use our hard work and diligence to scam potential renters into divulging all their personal info so they can engage in identity theft.

Result: Cash on Cash return = $7,77.31/$22497.50 = 30.5% (= not a scam calculation)!

However now I'm hearing stories that they may be a scam or some type of pyramid scheme.

It all sounds like a big scam.

For example the saying “If you believe that, I have some waterfront property in Florida to sell you” literally comes from Cape Coral, due to real estate scams there going back 100 years. 

I was mindlessly scrolling Facebook shortly after this and saw a friend from HS (who was not the best kid nor the most intelligent) accepting an invite to an event called "How to make $50k in a month" and I figured it was the biggest scam ever.
