think about this parable.......
moral of story: don't kill the weed which would in turn harm the wheat. same as don't kill the clones/trolls. u may end up harming a geniune poster.

i like this parable. very true.
but people here believe in and follow the practices of the Chinese saying, "rather wrongly kill 100 people than allow that one person to get away scot-free".
