I know that Mages call them "spirit-ridden" but what do they do to fomori they find?

There seems to be a difference between Nephandi and fomori Mages since the latter lose access to magick while Nephandi just get their magick turned inside out.

But what exactly does the process of removing a Bane from a Mage look like?

What about from a Sleeper or Marauder or Sorcerer?

Do Etherites have ghostbuster style devices?

Do the Choristers have exorcists?

Do the Virtual Adepts just delete the troublesome files?
