We have contacted Steam, GamersGate, etc about this and never even received a reply back.
I doubt they will. Since Steam holds a zero tolerance to cheating. But am not sure about the non DRM sites.
Another note for players using DAO/Awakening or the Ultimate edition. Can probably use their key via origin. Cause I have it on there as well.
