ACCESS DENIED: Venezuela is blocking websites people use to track exchange rates on the black market at a time when its citizens are scrambling for dollars while their own currency is in free fall.
SKIRTING CONTROLS: Bitly, the popular site for shortening Web addresses, has been caught in the crossfire. With the blocks in place, many sites managed to skirt the controls by migrating to Twitter, keeping hundreds of thousands of Venezuelans informed of the black market rate by using Bitly to direct traffic to newly created websites.
MOUNTING WOES: President Nicolas Maduro accuses the sites of fueling an "economic war" against his government. Government opponents say the controls are designed to obscure reporting of the nation's mounting economic woes.
