Glassdoor.com is in hot water after federal investigators in the US sent a subpoena to unmask anonymous users who might be "third party witnesses" to certain business practices by a company under investigation for fraud.

Can DevRant (@dfox, @trogus) be forced to unmask its users (IPs, emails) in a any way, by the US government (@fbi, @cia, @nsa) or any other government (@svr_rf, @mss, @mi6, @bnd), should a similar situation arise?
