Hi,
I don't think I could explain it to you, I bought his script and he is perfect.
But from what I've observed, he doesn't detect that he already has a player in the spot.
That makes a lot of difference, it drastically reduces bans.
I used another crab script, it doesn't even compare to yours, yours is infinitely better.
But the other detects that there is someone, and changes servers until it finds the spot empty.
