Whatever you do won't stop clones or spammers.
The way things work in international forums is to ignore those
posts by them, and quickly shoot off a PM to the
moderators/administrators who are online at that time for them to
take action.
Mass banning is doable, as some forums have this feature.
As stated, an average forumer doesn't start so many topics in one
day, so it's possible to limit that.
We can also have the warning system, but I doubt sgF wants it
again. Because we used to feature threads in such a manner and it
resulted in abuse. If clones were to use this feature, many
innocent people will get banned and there will be a lot of work to
do to unban.
Some forums have gone all the way to banning free email accounts
from being registered. Although this isn't a popular move, still
people signed up for it. Clones and spammers have too many free
accounts to abuse.
But then again, Starhub don't provide users with a free email
account... so it's not doable. I'm not sure for PacNet. Singnet
users do have one account.
