Even OpenVPN seems to be detectable, there's a provider that suggests running it over an extra TLS tunnel[1]. The overhead must be terrible, though.
You basically need to look at traffic patterns. A TLS handshake (HTTPS) is very distinct from a typical VPN handshake (except maybe OpenVPN since it uses TLS)
Or they can just block/throttle IP's of VPN providers. Not a lot of people can set up their own VPN server.
