You're clearly intelligent...
https://twitter.com/JorgeStolfi is this you?

What a waste of a brain. [ ... ] you just display opinion like a troll, and generally speaking you don't back anything up.. its all your opinion

I don't think I have ever seen you this defensive. You certainly aren't convincing anyone. [ ... ] Thing is, its obvious that he is not as stupid as his points. Which is another big red flashing signal of why I think he might have ulterior motives for being here. Like payments. [ ... ]
His background vs. his commentary doesn't add up. What does add up, however, is that he admits to having a decent size family to take care of, we know the economic situation in Brazil is very difficult and we can suspect a professor doesn't necessarily make much to take care of a such a family. He would be a perfect choice as a paid troll.

IMHO you're lying to yourself and us about your position [ ... ] still find hard to believe given your background.  BTW, have you learned how to use bitcoin yet, professor?

you're still assuming that JorgeStolfi @ bitcointalk is actually Jorge Stolfi...
