I remember someone is already trying to do that.
I faced one trouble last week. After doing several thread red, (I was going systematically page wise), I realised that some of the threads were not getting there fast.
When I opened multiple windows, only in case of some threads it was counting only one for each time (irrespective of number of pages it is open on).
I have read somewhere it also checks IP address.
Can someone help with the optimal way to do it?
(It is easier now to maintain these things with so many people active and contributing)
