anti bot system

Alright, so this system works by three methods!, lets explain them out!

Method 1:
On Player Join check if his name got _ symbol if yes split player name from first word to _ symbol.
then check if other players got same ip as the joined player and got the same name until their _ symbol
if a player got the requirements will count him as bot, if count reached 8 or above we will ban him.

Method 2:
When Player Join we will check if player name got two / one number on its last characters if yes we will split player name characters before these numbers
and check if any other players got same ip and same characters as this player's in their name
if yes we will count them as bot when count reaches 8 or above we will ban the player.

Method 3:
On Player Join, Split Player Name to two halves and check if seven other players got same ip as his and
also if got same characters as this player name halve one characters, if yes count them as bot
if count is more than 7 players we will ban him.

Method 4:
When Player Join we will check if server start time is more than 30 seconds [ to avoid bans on server restart ]
if yes we will get player ip and search if other players got same ip if yes
we will check if the matched ip players join time is less than 20 seconds
if yes we count them if count reached 10 or above we will ban the player
