If heroku got enough complaints (relative to it's size) they would get shut down or asked to leave. Now, heroku has a lot more than two servers, so it's going to take more than one or two complaints to take them out, and they are probably going to get more than an hour of notice, but if you provide a hosting service, you need to make sure that your users and customers are not using your service to host phishing sites.
