The agency I used to work had a few medical clients. One of our task was to make fake quora profiles and write up fake answers to promote these clients.

For example, somebody asked "What's the best cardiologist in [area name]?"

And we made a fake story like "My grandpa needed to get checked with a cardiologist and we visited (clients name) and they were great"

How is Google going to check the originality of these answers?

I thought about it because Google is showing a lot of UGC sites.
