Have you ever had Wiimmfi kick you out during an online match all of a sudden? (i.e. getting error code 91010) Since I patched my Wii with Wiimmfi, I've only had this happen once, and my name showed up on Wiimmfi's ban list. Any other times the game simply told me that I lost connection with the other players, but Wiimmfi didn't count that as a kick or ban.
