Removing replay hiding has an additional benefit - it makes prep less about busywork of finding people's posts on the forums and more about, you know, actually preparing for a game against them. Non-official tournaments should simply enforce playing tour matches on smogtours rather than allowing people to play on main (I know in, for example, randbats they prefer main because of constant balance updates that get pushed to main earlier but scouting is also not really an issue in randbats afaik). It's not a skill element of the game to have time to search the forums or friends/helpers to do it for you, it's just another time waster added onto a game we're all playing in our free time in between more important things and it decreases the accessibility of tournaments to people who don't have time to meticulously search, incentivizing everyone to hide every single replay they can and inconvenience their opponents too.
