# Assumming brute force attack has constant hit rate, says X hit per Y seconds, across enough long time range, says T seconds. 
# Every time we block a suspisuous ip for a period of time and unblock it, 
# we should wait T seconds to see if there were further attack with rate X/Y hit/seconds.
# If this ip still has attack action during T seconds with hit rate X/Y, send it to block list which has doubled block time.
