Last year, Nepal banned an Indian couple from climbing in the country for 10 years after they faked a photograph showing them on the summit of Everest.

Now, climbers attempting the world’s highest peak this year are supposed to wear GPS tracking devices to stop frauds, as well as to track those in distress. On June 5 2016, Dinesh and Tarakeshwari Rathod, a married couple, announced at a press conference that they had summited Everest successfully. They claimed to have stood at the top on May 23. They were granted a certificate from the Nepalese government, acknowledging and validating their climb.
