granted is not easy but "you only attract trouble (and a very few well-meaning people): spammers, script-kiddies, pirates" to give a bit of credit to the HN community most of the applicants were, in my opinion, well-meaning people ranging from students in College to developers looking for another playground. Most of the things loved by spammers (e.g. emails via localhost, remote connections) are not allowed so I don't think it would be so interesting to trouble makers. For storage there are so many free solutions that I doubt that anyone would even bother with this but...you have a good point and we are doing our best to keep the trouble makers away and monitor the system with a fast kickban action when needed ;)
