Bannerlord will have some form of anti-cheat, but what exactly & how effective remains to be seen.
Smurfs are an interesting problem, and privacy/data legislation potentially makes it more difficult to handle. Something as simple as a MAC address could out most smurfs, and raise the entry barrier for successfully smurfing to a point most people wouldn't bother with (requiring networking equipment & know-how most people don't have or understand). However, I don't know if the game could retrieve that information, or if it would be legal to do so given the unique nature of each MAC address.
