Yeah, they tried that with me, I told them to shove it, they were like 'k,k we don't want it anymore, just pls stay.'i don't know how many hosts do it, but when i signed up for hostgator i had to send them a photo/scan of my ID with a photo on it.
proxies, vpn, vps will solve the ip problemsif ur host is gonna release ur info anyway, ur gonna be screwed anyway what with your IP being logged into the host
