Why do people do this?

Me

I was looking at the puppies on Craigslist and came across two posts about some Yorkies. What first attracted my attention is the fact that they used a lot of emojis but that’s neither here nor there. I looked at both pictures and saw that they were fake. Why post a fake picture? The picture below is what was shown. I messaged them asking if they had any real pictures but I haven’t gotten a response yet.
