I'm running Ruby on Rails on a shared host that doesn't actually support it. And their abuse team has been in contact with me, claiming that Ruby (the actual ruby executable that I installed ... is listening on port 3000).

I am running Ruby on Rails as cgi and am not running webrick or mongrel or anything like that ... is this possible or are they just screwing with me? It took a bit of work to set up, and don't want to remove it if I don't have to.
