I think only scammed ICO are banned or how it will go about in the future. Steps will be taken to make sure Scam ICO cant be run in the first place and only legal ICO can run. This can be done by registering the ICO through some authority who will check the status and give the grantee that ICO is legal or maybe take some money as a backup so that no one cant even think of scam.
Need to be patient and see how things turn out in the future.
