Ask Fedora being badgered by spam

Hi, Of late, Ask Fedora is being badgered by spam. They seem to open multiple accounts and post as many as 50 spam questions at a time. Is there something we can do to tackle this? For the time being, we're manually blocking the user and deleting each question one by one. It's a lot of work and one needs to keep an eye out on the forum all the time. I've asked upstream a question here: http://askbot.org/en/question/12506/how-do-i-mass-delete-all-questions-fr... This is a work around to clean up the mess. Can we do something to avoid it altogether? I've asked upstream another question: http://askbot.org/en/question/12507/alternatives-to-akismet/ -- Thanks, Warm regards, Ankur (FranciscoD) http://fedoraproject.org/wiki/User:Ankursinha Join Fedora!
