Are you the forum cop? The only reason why I register is to have access to the mods part of the forum. I had an account perma banned because of a mod that doesn't like me and none of the many games I had registered can have the serials unlocked and no one from Paradox is has answered me when I ask to have those serials released or transferred. Now I cannot access tech support or mods for games that I paid for. I had to repurchase EU 3 just to get access again. So I only register a game if I really want access to mods these days. Not everyone is obligated to register their games. There are perfectly good reasons to not do it.
