I don't know if you remember
this thread I made a while back, but it pretty much sums up what the worst of the worst here do as far as creating and posting in idiotic spam threads. Now, I have no idea whether the ones I caught were from the Philippines or not, but I would certainly argue that they're well-represented among the most egregious shitposters. I strongly suspect that when families and/or groups of friends are all in signature campaigns, they collaborate and do shit like what you see in the thread I linked to.
It's no wonder bitcointalk has such a spam problem, and from what I've seen most of it comes from just a few countries, and the Philippines is one of them. I've said that before, and I got branded a horrible racist because of it, but it's true.
