http://www.form2pay.com/publish/publish_form/177365 Just contacted them via Live Chat. Apparently they offer hosting and those phishing sites are built by their customers. They delete them, when notified.
Update 2015-11-16: Phish: http://www.form2pay.com/publish/publish_form/181295
Unfortunately they don't keep up deleting those forms and don't take measures to ensure their site does not keep being abused. I start suspecting, they don't care.
