Wait.. so you added the enter thing b/c the hacker doesn't drop in the first 3 seconds? That's pointless.

Most hackers will just troll the lobby. They spoof a name, astat the game, boot all the players, then leave. Rinse and repeat.
It's rare that a hacker will get into a game, then /win hack in the first 3 seconds.
Most people that know that a hacker is trolling them will /stat and /whois every player in the game, or if they have the hacker's real name, just /whois him repeatedly.

Overall, most hacking to rape the entire game happens a) in the lobby, and b) when they are losing in game (mid/late game). They will rarely hack within the first 3 minutes of a game, let alone first 3 seconds. Also, if you detect the player hacking, why bother making another condition to detect enter. If they are caught, just drop em.

You did not understand, the anti hack takes 3 seconds to scan all the players, then drop.
Drophack is detected in the first 0.2 seconds, but it can't drop while the complete scan is in progress, so that's why the Enter thing is useful.

I guess I didn't get to the / yet then.

no, it detects / just fine, just not when you only press it down for one frame.
