Worldwide Campaign to stop the Abuse and Torture of Mind Control/DEWs
There is a video that has a very interesting approach to canceling out the effects of targeting (there's heavy use of Epsom salt/Magnesium Sulphate here too). He's a bit belligerent, but then what he is proposing is worth trying. It doesn't look like it will be excessively costly, and it might just work. I've certainly done crazier things in the name of ending OS.
I'd be interested in some feedback once you take a look at the links. His reasoning seems sound, if the premise upon which it is based is correct.
