But any site with unmoderated or poorly-moderated comments could be peppered anonymously with this sort of rogue link, so just forcing all your community members to create an account on your site is not itself enough to control this sort of abuse. Creating clickable links in many, if not most, online source code repositories is surprisingly easy, and automatically follows the look-and-feel of the site as a whole.
