I have a Twitter application so users of my application shares links of my webpage inside their tweets. It seems like bots follow these links and some of these bots create high bandwidth usage. And most of them doesn’t provide me any hit. So I want to disallow them with robots.txt, or .htaccess file.
My conecern is will it be a problem to ban Twitterbot ? Who owns this bot ? Twitter.com or other website? What would be the drawbacks to disallow it ?
