ROBOTS (fake users) ON MYFITNESSPAL to Advertise

Does myfitnesspal use robot fake users to advertise supplements? MFP wants to earn money. One easy way would be to deploy robot (fake friends) to advertise supplements. These so called friends could also keep you motivated so that you remain using the system. Robot fake friends can be used in my ways to increase MFP cash flow. Why do I say this? Things that my friends post will indicate how great a supplement works, just like an advertisement would. Follow-up with these friends is gibberish. I have had users contact me about diet and exercise help, but only after I pay for the help. I change my diet groups and many friends then have that same exact grouping, I could go on and on. So, does myfitnespal use fake people to advertise products? I think they do. Be very careful how you interpret diet plans of your friends and other users.
