I don't know what Futaba is.
Futaba is also known as 2chan. It's Japanese. You probably don't know that either. Simple enough to say that Ai-chan has nothing to do with it, though we did organize a mob lynching/hacking of mangatraders websites for stealing and making money off scanlator works during the time when scanlators operated secretly and never asked for money/donation. 4chan was amazing when it comes to gathering hackers together to deal with a crowd injustice. Many Anonymous sessions were recruited over 4chan.
So in short, it's basically a 'place on the net where everything used to be acceptable'. Nowadays, it's much tamer and its position as the 'place where everything is acceptable' has been taken over by the dark web. Can't be helped, since 4chan is indexed and the prudes of the west decided to slam legislation after legislation on it to the point that the site owner said, "Enough is enough! I've had it with all these lawsuits!"
For a while, there was a 5chan project after the site owner of 4chan buckled under legislative pressure. However, it didn't last long due to the same problems that 4chan suffered. From time to time, 5chan resurfaced, but disappeared again.
Anyway,
"My Chinese friend gave me a present, so I asked him "Who is this for, Chan?"
