I'm going to be very blunt and possibly very mean.
Anyone who thinks AF is real because a random website SAYS they're the "official" AF site needs to grow some common sense.
1) As stated, the site is obviously fake. For such an "official" site, it looks like a 15 year old Angelfire site. You ever see professional businesses with website do that? I sure haven't.
2) Whatever opening you saw was also fake. I've seen it. It's amateur editing and artwork that is a sorry attempt to mimic AT's art. It's fake.
3) SSJ5 goes too far as it is, but reading some of their laughable episode summaries, apparently there's a SSJ8 now where Goku becomes a giant like oozaru, but doesn't look like an oozaru. It's sad.
4) The episodes themselves are unrealistic and laughable. It's all a bunch of fanfiction passed off to be AF.
5) Have you seen their "forums?" No official company would use craptacular ProBoards as their official forums. Also in the links section is a link to someone's personal page, complete with bad grammar, l337 speak, and a lot of other amateur goodness.
AF means Annoying Fanboyism. In other words, some 15 year olds obsessed with DBZ got together, started the AF rumor, and is tricking DBZ newbies into thinking their crap is actually real.
Anyone fooled by this hoax needs to be slapped in the face by the iron hand of reality.
