Rulings
Being goaded more than once by the same player is redundant.
If you goad a creature you control, it must attack, and it must attack a player rather than a planeswalker.
If a goaded creature can't attack for any reason (such as being tapped or having come under that player's control that turn), then it doesn't attack. If there's a cost associated with having it attack, its controller isn't forced to pay that cost, so it doesn't have to attack in that case either.
If you leave the game, any creatures you've goaded remain goaded until your next turn would have begun. They don't immediately stop being goaded and don't remain goaded indefinitely.
If a creature you control has been goaded by multiple opponents, it must attack one of your opponents who hasn't goaded it. If a creature you control has been goaded by each of your opponents, you choose which opponent it attacks.
Once a creature an opponent controls has been legally blocked, activating Sly Instigator's ability won't change or undo that block.
If a goaded creature doesn't meet any of the above exceptions and can attack, it must attack a player other than a player who goaded it if able. It the creature can't attack any of those players but could otherwise attack, it must attack an opposing planeswalker (controlled by any opponent) or a player who goaded it.
Attacking with a goaded creature doesn't cause it to stop being goaded.
