Well... what can we do? If we want to ban them using harsh
method like alerting the cyber police to track them down and get
them arrested, they'll surely retaliate full force. Who knows, next
time we must really be cautious in the streets liao..?
Anyway, the best weapon to deal with them is ignore their sickening
post lah. Or if you are smart enough to debate with them till they
can't utter any more words, otherwise it's not wise to let these
pests bother you.
