I have been a member in sps review form and while this site doesn't have any ties with Yona (I don't think she would do anything like that), she has cult-like followers who will attack and bash anyone that doesn't support her and supports other psychics (especially platform psychics on Etsy, Fiverr, bitwine, etc). I was also attacked for defending Anne and another psychic and not trying out Yona (I personally feel she is a nice lady and a good card reader but nothing more).
However, to be fair one good thing about sps review forum, is that the forum's owner is very fierce when it comes to taking down actual shilling accounts and has been threatened numerous times by fake psychics with lawsuits, curses and stuff but the forum is still up and thriving. She doesn't let such threats affect the actual freedom of speech of such members. Here the forum owner has taken down a post where I exposed Bitwine scammers by names and told me he/she feared they would or I would get a lawsuit because of my list. It's such a pity I can't post this list online but anyone who uses Bitwine, please pm me.
