You can mail and ask them. You don’t have to provide any other information unless specifically asked for. Different services will have different policies so it’s better to be safe than sorry. I’m saying this out of my personal experience because I’ve gotten mixed replies from different sites. I usually use paid VPNs like Ivacy to avoid using the same IPs most people use in freemiums but that’s mainly for security and other stuff. But if the slotting service isn’t okay with it then you shouldn’t risk it.
