I've been dropped by Bluepay as well. I can't remember if it was because I got a charge back or if it was because I was a hosting company. This was in early 2016.
As far as PayJunction goes I was only ticketing in to support@payjunction.com
There are two others on your list that are dropping hosting providers as well. 2checkout, and stripe. Granted I still have a stripe account but I am reaching out to them now to confirm. https://www.lowendtalk.com/discussion/145709/stripe-not-going-to-support-hosting-company-to-get-payment
