First off Lika2525 has over 30 reviews under his belt so your theory does not really work here. He has plenty of ladies, high end ones to that can verify him.
Now for Leogeo2017 it might work, but since he gave her much lower review numbers then Candice is use to getting, I doubt he is trying to get a feather in his cap as you would say. With such low numbers, It would be a bad idea to use her as a reference.
What I find odd is in her Twitter posts on June 25th she made the following comments
Candice Carter @GFECandice Jun 25:
I'm so sick of people using fake reviews to try and "bump" others down on the top 100.... I haven't even been to NYC this month.

If you provided a valuable service you wouldn't have to put other girls down to try and get new clients... because you'd have regulars! Ugh!
