I read somewhere that a node is banned for 24 hours.
However I found the Misbehaving() function which makes
state->fShouldBan = true;. But I could not find any other function that makes
state->fShouldBan = false;. It seems that banning is forever.
If banning is forever, I guess the node also removes the misbehaving peer from its neighbor list, right? But I could not find it.
