tpb-loop.js

var request = require('request')
  , counter = 0;

!function getResource() {
  request('http://thepiratebay.se/torrent/' + counter, function (err, response) {
    if (200 === response.statusCode) {
      console.log('Found something at http://thepiratebay.se%s', response.req.path);
    }

    if (counter++ < 10000000) {
      // Delay requests by some amount to be nice to TPB's servers.
      // ..or just remove the timeout completely. :)
      setTimeout(getResource, 100);
    }
  });
}();
