Most sites are covered with ads, BigFish only contains their offerings so it doesn't bother me at all. I won't visit websites that have ads all over.
BigFish offers quite a bit of different options so in order to put them all on the front page they really had no choice. All it takes is one click to get to your regular page, so once you know where to click you are back to your regular page.
Don't feed the Trolls
