It depends on affiliate program, if they will steal the players or not. Bet365 are known with excellent reputation and not cheating affiliates, so hopefully they will continue.
They were honest exactly by the .com -> .dk transition, I remember that. Because at the day of the transition I saw some weird numbers like minus players, asked what is going on and next day there were huge plus numbers caused by retagging.
Ask somebody at bet365 subforum.
