I found this blogspot with a list of scammers and "real" casters.
I can't speak much about them, I nearly used mother deity but because of her location I stayed away from her - she seemed alright but again, being from Nigeria I learned that those aren't the best to trust even if they seem trustworthy.

That's the blogspot, take a look. The list of the scammers are true, all of them listed as scammers are really scammers.
Take a look if you life. I'm just making everyone aware.
