FBI has already been contacted. FULL CATALOGUE OF PROOF & INFO below (press SHOW MORE) (UPDATE: He posted the video.)
For the conclusion of this; I tweeted Anita "Hey we caught someone responsible for a ton of these threats!! Let's work together to stop him!" but it was since deleted.
I have reached out again to her; it is Brazilian law that we need her to help report this man in order to stop him!

START HERE WITH THE SUMMARY:
IP Hunting / Death Threat Proof:
Here are his current twitter accounts as of 10/30/2014
And his posts on my youtube: http://i.imgur.com/lCyeicF.jpg
- My writing is a little off because I felt really panicked speaking to this person, not sure why, wasn't sure what to say.
- This will be a compendium. Please note the user changed names half way through. The last two archives show this is the same account.
- Mateus continually issued death threats against Anita AND any pro GG person defending her. Upon having his IP snooped, he stopped using threats out of fear but continued the harassment.
- "Who should bother to report me is Anita, and Anita alone, not you"
- "My team is working, we will hack her twitter profile soon"
- "Utah State University this week: NOT real threats, same here on twitter"
^(PS, we have zero proof he had anything to do with Utah, only twitter threats have confirmed IP's)
- "do you know what a troll is? and trolls say, I will kill you"
- "the authorities always seek the cases that present real risk, not a supposed threat from the other side of the country, it is quite funny"
- "in a few hours celebrinando guy (a team mate) will make a video about her, on youtube, her latest video, in 6 hours" - ~5 AM EST
- Transcripts below in Proof B)
