I guess the consequence would be to have a list of pretty good engineer at (maybe) lower prices for other companies, which would results in a competitive disadvantage. It would also probably have a chilling effect on other potential hires : I know that I would think twice to work for a company that has this kind of blacklist. And if they do have a blacklist, I would think it thrice if they put in a company like Facebook, when other companies have a way more disastrous effect on the world in general, even if there is more publicity about facebook at the moment. Finally, it would definitely be illegal to have at least european people on this list, but hopefully it would also be illegal in other jurisdictions.
