I've just been having a look at the TH website and noticed that for new tutors, joining after April 1st, there is a new system. Instead of collecting a finder's fee, TH collects commission of up to 25% on every lesson. Bookings and payments are handled by TH rather than directly with the tutor. I certainly wouldn't have signed up under those conditions. For the moment this doesn't affect existing tutors who joined before April, but I wonder if they intend to move everyone onto the new system eventually. Something to keep an eye on if you're on TH.
