Problem is that you guys can see the Chinese and Pakistani trolls who derail threads, but can't see the Indian trolls who come into Pakistani and Chinese threads and derail them. We know what to do with whom and what not. If they abuse and do some other act like that, they will get their punishment. If we can let many more Indian trolls online when they derail threads, then we can keep these guys also, as long as they don't cross the limits.
Common sense dictates, that if someone posts troll or stupid post, replying to it will make them post more, neglecting them will discourage them. And other best option is just to report the troll post and it will be dealt with.
Replying them makes them post more as it makes Indians go on a troll spree also.
You see troll post, report it. Let us do our work our way.
