People don't dedicate their lives to csgo, the amount of time it would take for anyone to get to 24 hours is insurmountable for anyone who has a life outside of their parents' basement. There are far too many negatives that adding this would cripple the amount of new players we get no one wants to play for most likely over a week just to play ct, we are doing all we can to have people learn the rules. At that point, if they don't learn them they probably will never learn the rules. this isn't a solution but rather stops ALL new players from playing ct not just rule-breakers.
This should never be increased because it only delays rule breaks for the amount of time it is increased unless it is an unruly amount at which point no one new would want to play the servers. After that point what's the point of hosting a csgo server if you don't want new players.
we have the rule pop up every time you load in, there are regulars who spam the read rules bind, you have to wait 30 minutes before playing ct, and the server has messages in chat about the rules and faq. There isn't much more we can do that wouldn't discourage people from playing our servers, things like this have been suggested again and again but have always came to the same conclusion that it is too much past what we currently have.
