HippoJo’s Management has been around since dinosaurs walked the earth. They started over 30 different online casinos in the past and I have little doubts they retained affiliate and player contact info from all of them. While its possible they crawled our site I think its more likely they had your email addys from elsewhere.
They are set to come onboard here at CAP and are just now going through our due dilligence process. I will talk with them and let them know that spamming isnt a good way to endear themselves to potential new affiliates.
