Bannies are the lowest lifeforms on BZPC.
It is best to laugh at them when they appear.
Not to mention it is traditional to randomly kick them. In recent times JediBot got CHAIN KICKED FOUR TIMES IN A ROW!!!!!! and got really angry at Invictus for starting it and blamed it all on him his new comic series wouldn't have PGSes.
The most bannies ever online was on July 26th, 2013 during the Second Day of the Replicas.
