TL;DR It is possible for her to develop that accent and fluency within a year and a half. Exceptional? Yes. Impossible? No.
Have fun 
I agree, accent and fluency can be learned in as little as a year, but only if you actually spend time with native speakers, immerse yourself in the language and culture, and really work hard on an accent/language improvement course. The video I saw was from 2011, so she had like 1.5 - 2 years to do this. Now, some people are probably completely exceptional and can learn all this by doing nothing but spending time with ESL courses, watching american media and reading english internet discourse..
However, the evidence is scant on whether she's actually spent this amount of time in the U.S. or if she's really a polyglot/linguistic geek/savant. Google's not giving me enough info on her whereabouts or activities, and her Facebook page is nothing but photos of her in auto shows and cosplaying events.
I personally have nothing against the OP, or anyone else here, and I think the platinum duo was great. Just my 2c.
Agree with your 1st paragraph 100% (and your third

) (as to the second I thought it was mentioned she had moved to US, no? If not then yes, she would have to be very exceptional. However, no-one has posted any evidence that in any way proves she is lying. I think we got two pages of looking at the wrong profile, no? Lots of tinfoil hat / I am jelly, but nothing of substance.
I am only posting because it is my area in more ways than one. And because while gamer groups hate the stereotype they get some will still immediatly assume that stereotype is correct and try to reinforce it. So therefore, it is not possible that someone successful in life would play this or any other game... especially if they are female and good looking and even more so, really or even slightly famous.
I find the irony of that to be the most unbelievable thing in this thread.
Have fun
