I think i can answer that. I read a lot on bitwine (still on progress to stop completely) and I think I read with so many readers that my names are on majority of their review page.
I'm not sure about whether the psychics put their own review. But for people who binge reading I think that happen a lot. Either they keep reading with the same psychic everyday for reassurance or they jump to many readers on daily basis (I definitely did. And much worse than now)
I hope that help at least a bit.
