What kind of cheating are you talking about? Years ago I came across some sort of multiaccounting "ring" with more than 100 connected accounts, that colluded to prematurely end late registration in satellites. For instance the satellite would require 6 players to start and pay top 3. Then a bunch of them would register in the last few seconds, before the tournament was cancelled, so that there were just the needed 6 players but no more.
And then in the very first hand 3 of them would move all-in preflop with, whatever they had, which would bring the number of players down to 4 and end late registration, before anyone else had time to join. In this way the satellite would run with a big overlay, so it was largely a way to cheat 888 Poker. I told 888 Poker about it, but for whatever reason after several month they had taken no action to stop it. And then I stopped playing there, so I dont know, if action was eventually taken.
