Reply Bots on the top 15 leader board

The Clever Little Cupcake Company (Amanda Mumbray) ...

Omg! I have just commented on a monster high cake in the top 3 this evening. All of the posts (except mine) seem to be fake accounts. If you look at the activity logs for all of the posters, they have only ever commented on her cakes, and have no cakes themselves uploaded.

It does my head in! Why do people do ths? Absolutely crazy, and very narcissistic!
