Hideout card is already in the game. This reduces danger. Very expensive way to reduce danger. (I only use on MoW if need be)
But I agree with Danik. When you hit with fleets that are in turn able to be hit back, your danger will go away soon enough.
One common fella who happily clears my danger all the time is CDV.
The other strategy is to hit with ships you don't care about, if you carry lots of ships and your sink chance is high. You can run up danger as high as you want. After 10 - 15 hits the ship is sunk and boom, no more danger.
Sloops and SoW at good to use in this case.
