According to the official resources, the Facebook discontinued the Poke feature on its main mobile apps in April 2012 and on its website and app completely in May 2015. The reason for this was that the Poke feature was no longer relevant and did not align with Facebook’s main goal. Facebook also aimed to forget its previous, unsuccessful experiments with “unbundling” and concentrate on its Creative Labs exploration. Nevertheless, you can still visit the Poke page by typing “poke” in the site or app’s search box, or by following the link to the page:
