ConveraCrawler is a bot developed by convera.com. It seems they are selling gathered information to third parties. The full user agent string for this bot is "ConveraCrawler/0.9e (+
http://www.authoritativeweb.com/crawl)". Most of the requests come from
63.241.61.7, however I also saw requests from
63.241.61.32 and
63.241.61.52 IP addresses.
