Some hyper aggressive lines against Scandinavian??
If you play the Center Counter Defense if 4.b4 Black's alarm bells should be going off. It can be tricky line to play against. From my experience 6...c6?! which normally is a solid move in Mieses line is passive here. I prefer 6...a6 keeping my pieces untangled and allowing c7-c5 in one go if necessary.
Other tricky lines are 4. g3 4. f4
That said IMO once you have studied them, Black shouldn't fear them.

Are you sure it's not a dubious sac?!

Are you sure it's not a dubious sac?!
Yes, it is, in a classical time control game I wouldn’t dare to play it, not even as a joke.
But in blitz is fun and effective if you know how to play it
in online bullet many players mess up with the pre-move and lose their queen by move 4.
You have to have a well studied plan
White can choose to develop their bishop via c4 or g2.
There are several plans you need to know what to play because otherwise you’ve just given away a pawn for nothing.

Are you sure it's not a dubious sac?!
No, it is not dubious. One just needs to know how to utilize his mid-term positional advantage he has gained at the cost of a pawn. White has a slight plus score even at official correspondence chess level, where engine usage is allowed.
