There isn't really a way to help them until they decide that they want out. It is the same with any addiction (or addicting product) the user (abuser) will continue to dive deeper into their escape portal. Shutting down that portal without their approval is forcing the issue, and most likely won't result in a resolve. People need to escape, whether it be through all the other avenues listed in previous posts, the bold point remains that users (abusers) of this type will only come out of their hole when they make the decision to. Encouraging them to or helping them come out of their hole is all well intended; but as with my addictions in the past the only way I was going to quit or take control is when I finally decided enough was enough.
