Stuck on the logical order of how to do a command check timer.

I know there is no way to block nodus, premium, etc etc.
But ive noticed with regularity that quite a few mod clients send /plugin or /pl directly after login..and on a timed interval of about 3 seconds.

So Im trying to find a way to catch this, I know it wont stop the clients most of the time, and isnt a real 'solution' to the problem. But if I can kick people doing it with a message of "use normal MC client".

The issue I'm stuck on is I can get the command they send no problem, and make the scheduled task no problem, and even set an int to count how often they do it...
But I cant think of how to order/code the OnPlayerCommand to have it catch each time they do the command using my scheduled task to say "after 5 in X seconds, kick" or "if /pl is sent withing 1 second of login, kick"

So i got the basics of what parts I need to use (onlogin/onplayercommand/some int to count the times sent/scheduler to tick it all), just not how to put them together to achieve this.

 

If it's new users on their first login, you could do something like:
-New user logging in (event)
-If that NEW user types command : / plugin
Kick user.

 

pshedocode:

Code:

on every command:
  if(player.getLastPlayed() + (5*1000) > System.timeMilies())
    if command == /pl
      cancel command and kick player

no need to use schedulars whit the /pl check

 

oh wow, I didnt know about "getlastplayed" thats 100x easier than my idea.
