if you have admin on a server (and tools.cfg),
Though I might suggest you'll eventually want to change the threshhold ("trashhold," as Mr.Floppy says) values.
[SELECT ALL] Code:
alias autoban [loop p 21 [if (<= (at (pstat_score $p) 1) -8) [if (<= (at (pstat_score $p) 1) -10) [ban $p] [kick $p]] []]]
add2conloop [if (currole) [autoban] []]
