You can see other people picks even if they are not locked 100%. If you want to test it check my picks, they are not locked except for Sevilla game. I lock only the games which I bet on so I can check what you guys played and have some sort of reality check.
There is some possibility for abuse but that only comes into play in last rounds and you can always just tinker your picks 5 minutes before the game starts and make it almost a non issue. There is much more possibilities for abuse by multi acounting in our Premier League and we discussed it there in more detail.
it is possible to see other picks, but you have to lock your picks prior, or am I missing something, so if you lock your pick, it is of no use for the competition that you will see other picks, since you cannot change your own?
maybe, if you have two or three accounts, and one using just for the oversight for other people picks, but that would be too much of the effort for this pool? with BTC rising, reward is better, but it is just too much effort for a year to follow all picks, and you cannot guarantee success after all, it is just good for last rounds, if you are on the top, and have one follower, but you should came to the top in the first place
nevertheless, I do not see much of a worry there
other thing that I have spotted in some earlier rounds is that beginning times for matches in Superbru do not match with actual times, and that could be exploited (there were few examples, most notably Getafe - Villareal in Spain, few rounds ago, and I saw that there was a lot good picks on that match), Superbru lock those matches after first goal that is reported by their contributors
usually, I put my picks on Thursday/Friday, and do not change anything (whenever I changed, that did not brought me any luck)
