Because there are users on our server who sometimes like to play with their limits and stop spamming when the reached 19 of 20 allowed actions I added a new feature into the Antiflood module for Mumble Moderator today.
When a user reached half of his allowed action limit there is a randomized test whether to kick a user even if the full limit it not reached yet :P
In such a case the server kicks the user the the kick reason „Oh, did I miscount?“.
It is activated by default but can be disabled.
You can get the Antiflood module on Github.
Its documentation can be found in my wiki, see here.
